INTRODUCTION
Your new Vector MAXX SST inverter is one in a series of the most advanced DC
to AC inverters available. With proper care and appropriate usage, it will
provide years of dependable service in your car, truck, RV or boat.
The MAXX SST supplies continuous power and peak watts, in the form of three
plug-in outlets ready to deliver 110/120VAC power whenever and wherever
you need it! This inverter has enough power to run most
household or electronic appliances. Added safety features include automatic
shutdown and a low battery alarm to prevent damage to your battery.
This Power Inverter is configured with the latest Soft Start Technology (SST).™
Before introduction of Soft-Start, high start-up currents from large inductive loads
could shut down the inverter. Soft Start improves inverter operation by:
1. Gradual voltage ramp-up during inverter start-up. This eliminates failed cold
starts under load.
2. Output that momentarily dips in voltage and quickly recovers to allow
large motorized loads to start. This eliminates almost all shutdowns from
momentary overloads.
3. This power inverter also incorporates a new cooling technology. The new
design cools the power transistors more efficiently, and combined with Soft
Start, dramatically increases reliability and the life of the product.
1.1 BASIC TOUR OF THE MAXX SST™ MODEL INVERTER
AC power is supplied via three standard North American grounded, plug-in
receptacles (U-ground) as shown in FIGURE 1 (#1). This allows the connection and
operation of most 110/120VAC powered electrical and electronic
appliances.
Other front panel items are:
One green LED (#2) that lights when the inverter is operating.
One combination over-temperature and overload LED (#3). If this lights, the
inverter will automatically shut down.
One on/off switch (#4) that shuts off the AC output and all inverter functions.
The on/off switch is also used to reset the inverter, after shut down, due to overload
or over-temperature condition.
FIGURE 2 shows the back panel DC connectors and fan locations. Note: The
fan only operates when the inverter’s load requires it to operate. It shuts off
when cooling is not required.

1.2 MAXX SST SAFETY FEATURES
BUILT-IN AUTOMATIC SAFETY FEATURES INCLUDE:
• Overload and over-temperature shutdown activated if AC output
exceeds rated watts
• AC short-circuit shutdown and automatic reset
• Low voltage audible alarm and reset
(sounds at 10.6 volts input)
• Low-voltage shutdown and automatic reset
(activates at 10.0VDC)
• High-input voltage shutdown (activates at above
15.5VDC) and automatic reset
WARNING: MAXX SST™ output should be treated with the same caution
as any 110/120VAC circuit. It is very important that installers and users read
and follow all instructions provided in this manual to ensure optimum safety
and performance.
5
MAXX SST™ inverters are ideal for powering:
• TV/VCR combinations
• Refrigerator/freezers
• Lights
• Radio receivers/transceivers
• Heavy duty power tools & chargers
• Stereo systems
• Small microwave ovens
• Household appliances
• Computers and peripheral equipment
• Dry and/or wet-and-dry vacuums
• Sump pumps, motors and other electric-powered equipment
MAXX SST™ uses a 12VDC power source like those found in motor vehicles, or
it can be operated using multiple battery configurations with commercial battery
chargers or solar battery chargers. For most heavy-duty applications, a multiple
battery configuration and the use of deep-cycle batteries is required.
When using multiple batteries, inverters can be operated from one of the vehi-
cle 12 volt batteries, so there’s always one battery with adequate charge to
start an engine.
MAXX SST™ includes a high-surge capability. This is required to start heavy
loads, such as motors and other inductive devices.
1.3 APPLIANCE CAUTIONS
NEVER plug small appliances into the inverter outlets to directly recharge nick-
el-cadmium batteries. Always use the charger provided with that appliance.
NEVER plug in battery chargers for cordless power tools, if the charger carries a
warning that dangerous voltages are present at the battery terminals.
Some fluorescent lamps may not operate properly with this type of inverter. If the
bulb appears to be too bright, or fails to light, do not use the lamp with this inverter.
Some fans with synchronous motors may slightly increase in speed (RPM) when
powered by the inverter. This is not harmful to the fan or to the inverter.
Certain chargers for small nickel-cadmium batteries can be damaged if
plugged into the inverters.
DO NOT use inverters with the following two types of equipment.
1. Small, battery-operated appliances such as flashlights, cordless razors and
tooth brushes that can be plugged directly into an AC receptacle to
recharge.
2. Certain battery chargers for battery packs that are used in some cordless
hand-tools. Chargers for these tools have a warning label stating that
dangerous voltages are present at the battery terminals.
The majority of portable appliances do not have this problem. Most portable
appliances use separate transformers or chargers that plug into AC receptacles
to supply a low DC or AC voltage output to the appliance. If the appliance label
states that the charger or adapter produces a low DC or AC voltage output
(30 volts or less), there should be no problem powering that charger or adapter.
6
2.0 INVERTER APPLICATIONS
Aside from issues of supplying power to higher wattage appliances, inverters
must be supplied with a constant source of high current 12VDC from a bank of
batteries. At full watt load, the DC input requirements are up to 15 amps at
12VDC.
Read and comply with the following applications, and your inverter will give
you years of reliable service.
WARNING: Never connect the inverter’s AC output to an
AC distribution system.
2.1 UNINTERRUPTIBLE POWER SUPPLY (UPS)
Inverters can be operated as uninterruptible power supplies that continuously
provide AC even if outside AC is interrupted. This function continuously
operates the inverter from a battery bank, simultaneously replacing the charge
to the battery bank with an AC-powered 12 volt battery charger. Charging can
also be by means of a solar charger system. (See FIGURE 3). The charger must
be selected to operate continuously in order to fully replace the charge on the
battery as the inverter operates. In this configuration, the battery "floats" on the
DC from the charger, not really supplying power or being charged. When out-
side AC fails, the inverter continues to power the appliances for the life of the
useful charge of the battery bank. When outside AC is restored, the batteries
are charged as the inverter continues to operate. Battery charging must be
sized to replace the average current supplied by the inverter plus a little more
current. Another requirement is that the battery charging rate cannot exceed
10% of the Ampere Hour (AH) rating of the battery bank, otherwise the life of
the batteries can be dramatically reduced through overcharging. Most modern
battery chargers automatically adjust the charging rate based on the state of
charge on the batteries they are charging. For this type of operation, use deep-
cycle batteries and avoid charging at too fast a rate.
Common unattended applications for the UPS (floating battery) include power-
ing: sump pumps, safety lighting, communications equipment, burglar alarm
systems and computer systems.
Figure 3 – Uninterruptible Power Supply

3.0 THEORY OF OPERATION
MAXX SST™ inverters change 12VDC into 110/120VAC RMS, electrical power.
This is accomplished in two steps. (See FIGURE 4).
The first stage raises the 12VDC input to 145VDC. The advanced design
of the DC-to-DC first stage uses high-frequency conversion techniques
that replace bulky and heavy transformers found in older inverter technology. The
output stage changes the 145VDC to 110/120VAC. This solid-state circuitry
ensures excellent overload protection and the ability to operate reactive loads such
as those found in inductive motors. The inverter’s output stage uses multiple banks
of metal-oxide semiconductor field-effect transistors (MOSFETS). This stage functions
as a high-power bipolar switch, alternately applying opposite polarity to the AC out-
let HOT and NEUTRAL terminals.

and Fuse
Amperage

Figure 4 Simplified Diagram
Some Models only include volt, Amp and over temp indicators.
The 110/120VAC output of the inverter is in the form of a modified sine wave
(MSW) as shown in FIGURE 5. This type of waveform has the same energy char-
acteristics as the sine wave of commercial electrical power. The modified sine
wave is superior to the 100% square wave output (not shown) produced by
most other DC-to-AC inverters on the market. A modified sine wave, as com-
pared to a square wave, is vital to the efficient and proper operation of certain
appliances such as computers, TVs, and certain electronic equipment.
Figure 5– Modified Square Wave and Sine Wave Comparison

NOTE: Because of wave-shape differences, using standard digital or analog
voltmeters may not correctly read the inverter output voltage. Unless a true RMS
voltmeter such as a "Fluke 87", "Fluke 8060A", "Beckman 4410" or "Triplet
4200" is used, the reading will be from 2 to 20 volts low.
4.0 OPERATION
NOTE: Ensure that the total continuous power consumption of all tools and/or
appliances connected to the inverter (and in use) does not exceed the inverter’s
continuous watts rating. Also ensure that the start-up wattage for inductive
loads does not exceed peak watts for more than a second.
CAUTION: Appliances such as microwave ovens will normal-
ly draw more than their rated current and could possibly overload
the inverter when operating simultaneously with other appliances.
For example: A 600 watt microwave oven draws approximately
940 watts.
4.1 POWER REQUIREMENTS:
Most electrical tools, appliances and audio/video equipment have labels that
show the unit’s power consumption in amps, watts, or both. To avoid inverter shut-
down and possible damage to the inverter, avoid exceeding the watt rating of
this unit. If the power consumption of the tool or device is rated in amps, multiply
the amps by 110/120 VAC to determine the wattage.
For instance, a power tool rated at 4 amps will draw 440 watts. The inverter
has built-in overload protection so that if you do exceed the watt continuous
duty limit, the inverter will automatically shut down. Once the excessive load is
removed, the inverter can be restarted and resume normal operation.
Note: To restart the inverter, turn it off, and on. The on/off switch is located
on the front panel of the inverter.
The inverter powers resistive loads the easiest; however, larger resistive loads,
such as electric stoves or heaters, could draw more wattage than the inverter
can deliver on a continuous basis.
The following chart shows the approximate amperage at 110/120VAC and the
corresponding wattage at 110/120VAC for various common tools
and appliances.

NOTE: APPLIANCE SPECIFICATIONS MAY VARY FROM BRAND TO
BRAND. THIS TABLE IS OFFERED ONLY AS A GUIDE TO APPROXIMATE
POWER RATINGS. CHECK APPLIANCE MANUALS OR PRODUCT LABELING
FOR ACTUAL RATINGS. TO USE THE MAXIMUM OUTPUT OF
CONTINUOUS WATTS, MAXX SST MUST BE CONNECTED TO A DC
POWER SUPPLY CAPABLE OF PROVIDING 1/10TH OF INVERTER’S
CONTINUOUS WATTAGE RATING.
A. Power Output
The inverter will operate most AC loads within its power rating. Some induction
motors used in refrigerators, freezers, pumps and other motor-operated equip-
ment, require very high surge currents to start them. The inverter may not be
able to start some of these motors even though their rated current draw is with-
in specifications for this power inverter.
If a motor refuses to start, observe the battery voltage using a DC voltmeter while
trying to start the motor. If the battery voltmeter drops below 11 volts while the
inverter is attempting to start the motor, this may be why the motor won’t start.
Make sure that the battery connections are tight and that the battery (or batteries)
is (are) fully-charged. If the connections are good and the battery is charged,
but the voltage still drops below 11 volts, you may need to use a larger battery
(or battery combination).
B. Input Voltage
The inverter will operate from input voltages between 10.5 and 15.5VDC. If the
voltage drops below 10.6 volts, an audible low battery warning alarm will sound.
The inverter will shut down if the input voltage drops below 10.5VDC. This built-
in feature protects the battery from being completely discharged.
The inverter will also shut down if the input voltage exceeds 15.5 volts. This
protects the inverter against excessive input voltage. Although the inverter
has built-in protection against over voltage, it may still be damaged if the input
voltage exceeds 15.5 volts.
NOTE: Exceeding recommended voltage limits will void manufacturer’s warranty.
10
Inductive loads, such as TVs and stereos, require more current to operate than do
resistive loads with the same wattage rating. Induction motors, as well as some TVs,
may require two to six times their rated wattage to start up. Because the MAXX
SST™ inverters have a peak watt power rating, many such appliances and tools
may be safely operated. The equipment that needs the highest starting wattage are
pumps and compressors that start under load. This equipment can be safely test-
ed. If an overload is detected, the inverters will simply shut down until the over-
load situation is corrected. Use the front panel switch to turn OFF the inverter,
then ON, to reset the inverter.
CAUTION:
NO USER-SERVICEABLE COMPONENTS INSIDE.
OPENING UNIT WILL VOID WARRANTY.
4.2 DETERMINING BATTERY SIZE:
To determine the minimum battery size that you will need to operate appliances
from MAXX SST™ Models, follow these steps:
1. Determine the wattage of each appliance and/or tool you will need to
simultaneously operate from the inverter. To do this, read the labels on the
equipment to be operated. Usually, power consumption is shown in watts. If
it is shown in amps, multiply by 110 to determine the wattage.
2. Estimate the number of hours the equipment will be in use between
battery recharges.
3. Determine the total watt-hours of energy use, the total running time and the
average power consumption.
To get an estimate of the current (in amps) that the battery must be capable of
delivering, divide the load consumption power (in watts) by (10). Keep in mind
that most appliances are not operating for long periods of time. For example,
a typical home-use coffee maker draws 500 watts during it’s brew time of 5
minutes, but it maintains the temperature of the pot at about 100 watts. Typical
use of a microwave is only for a few minutes, sometimes at low power. Some
exceptions to brief operating times are lamps, TVs and computers.
4.3 BATTERY OPERATING TIME
FIGURE 6 is a set of curves that show how appliance load in watts or in
amperes affects operating time. These curves are only estimates of operating
time, dependent upon:
• The condition of the batteries
• The state of charge on the batteries
• The amount of other DC appliances drawing current from the batteries
Three curves were developed for a battery of 50 Ampere Hours (AH) capacity,
and three for multiple batteries in parallel. The higher capacity curves are for
120 AH, 200AH and 400AH capacities. These large capacity batteries clear-
ly extend operating time at full load. To extend operating time in general,
reduce the heavy appliance load to a minimum. Remember, you are operating
on stored energy and probably under power loss conditions. All operating time
curves assume permanent installation with the correct DC input wire (See Specs
Page 18) and a full charge on the batteries.
11
Figure 6 – Battery
Operating Time
For example, as shown in FIGURE 6, using a 400 amp hour battery (batteries),
if the average power usage will be 1000 watts, the operating time will be
about 150 minutes. A larger capacity battery will deliver more operating time
between recharges.
NOTE: The manufacturer recommends conservative estimates when selecting a
battery. More amp hours will deliver a reserve capacity, and a larger
capacity battery will not be subject to deep discharges. Ideally, the
number of amp hours (AH) you expect to use should be less than 50%
of the battery’s rated capacity.
4.4 PROTECTIVE FEATURES
LOW BATTERY ALARM:
An audible alarm will sound when:
1. The 12 VDC power supply voltage drops down to 10.6 volts. This indicates that
the battery needs to be charged or there is an excessive voltage
drop between the battery power source and the inverter.
NOTE: It is normal for the alarm to sound when the inverter is being connected
to, or disconnected from, a 12VDC-power source. This does NOT
indicate a problem. However, if this alarm sounds continuously, discon-
tinue inverter operation and charge the battery before resuming operation.
If the voltage drops to 10.0VDC, the inverter will automatically shut
down.
If the low voltage alarm sounds when the battery is fully-charged, refer to the
troubleshooting table for possible causes and remedies. (Pages 19-20)
CIRCUIT PROTECTION: The inverter has electronic circuit protection against
overload or short circuit conditions.
WARNING: If turning the front panel mounted switch OFF then
ON does not reset the inverter, DO NOT ATTEMPT TO OPEN THE
INVERTER. Opening the inverter, for any reason, will void the war-
ranty. The unit must be returned to Vector Manufacturing, Ltd. for test-
ing and repair by professional factory technicians.
12
5.0 INSTALLATION
MAXX SST™ inverters will provide you with various watts of continuous, electrical
power (See Models Specification Chart Page 18) when powered by a 12VDC
source such as is found in a vehicle or multiple battery configuration as shown in
FIGURE 7. This manual does not describe all of the possible types of battery,
battery charging, and battery isolation configurations.
5.1 INPUT POWER REQUIREMENTS:
To properly operate the inverter, the DC power source must provide between
10.5 and 15.5VDC and nominally at 150 Amps. This DC power source must
be a well-regulated DC power supply as typically found in vehicle and
deep-cycle marine batteries. The DC power source may also be two 12 volt
batteries connected in parallel. On larger applications the power source may
be several batteries connected in parallel as shown on FIGURE 7.
Figure 7 –Battery Wiring
®
NOTE: Vector Manufacturing recommends that for typical heavy-duty uses,
a specified or equivalent main buss fuse (See Page 18) be added as
close as possible to the power source (battery) positive terminal. The
fuse amperage must be sized to allow simultaneous operation of all
the AC appliances to be powered, with delay characteristics that
allow for the momentary high start-up current requirements of inductive
loads. Use the recommended fuse block (fuse holder) and fuse, or an
electrical equivalent. For full rated output and motor start-up surge output,
ensure that the installation is configured to handle the full load. FIGURE 7
is also used as a guide when the cables are measured for installing the
inverter; available through Vector Technical Support toll-free at (866) 584-5504.
5.2 OPERATING ENVIRONMENT
WARNINGS: DO NOT locate inverters in an area, room or compartment
where explosive or flammable fumes might be present. Areas
such as: engine room, engine compartment, boat, and small,
unvented battery compartments.
13
In all marine applications, DO NOT install the inverter below or near the waterline,
and keep the inverter away from moisture and water.
Use ONLY non-corrosive marine fasteners and fittings for installation. Only con-
nect the inverter’s DC input to existing wiring (which must be approved for
marine use) rated specified gauge, cable and length. (See Page 18) For cable
lengths exceeding 6 feet from inverter to batteries, call Vector Manufacturing
for additional installation information. The cable, fuse holder, fuse (not sup-
plied) can be purchased at an electrical supply company. The fuse holder and
fuse are a specified amperage rating (See Page 18) fuse and appropriate fuse
®
holder. Call Vector Technical Support (954) 584-4446 or toll-free (866) 584-
5504.
CAUTION: To avoid possible dangerous conditions, the inverters must be
located where:
1. The unit is kept dry.
2. Air temperature is between 30°F (-1°C) non-condensing, and 105 degrees F
(40°C).
3. At least three inches of clearance from other objects is maintained for cooling
airflow.
4. The unit is not exposed to direct heat, sunlight or to explosive or
flammable fumes.
5. The unit is as close to the DC power source as possible.
CAUTIONS: This device supplies 110/120VAC electrical power directly to the
appliances through three standard, North American U-ground
receptacles. NEVER try to use the inverter with any 12VDC-
power source that uses a positive ground. Most vehicles, boats
and aircraft use negative ground systems.
Never connect the ground wire from the inverter to the DC negative input.
• CHECK to ensure that the combined loads of the appliances being powered
by the inverter DO NOT continuously exceed the inverter’s watt rating.
• NEVER place items on or over the inverter during operation
™
MAXX SST inverters generate heat during operation like any high power
device and must be placed where cooling air can circulate to the internal fan,
and heated air can be removed.
For optimum operation, the inverter should be placed or mounted on a flat
surface; ideally, a normally cool metal surface to help diffuse the heat that is
generated. Two specified cables (See Page 18) will be required (not supplied);
each should be a specified length (See Page 18) to allow for full power oper-
ation and to provide flexibility in positioning the inverter. For safety reasons,
keep small children away from the inverter at all times.
5.3 INSTALLATION SEQUENCE
To wire the inverter to a 12VDC power source, observe the following cautions,
and follow the installation sequence for Quick Operational Check and
Permanent Installation.
CAUTIONS: Ensure that DC connection polarity is correct. Reversed polarity
will blow a fuse and may cause permanent damage to the inverter.
The manufacturer’s warranty does NOT cover damage due to
reversed polarity. Review FIGURE 2, if necessary, to identify the
location of the DC terminals.
14
5.4 QUICK OPERATIONAL CHECKOUT OR EMERGENCY USE
YOU WILL NEED:
• One heavy-duty jumper cable set with specified AWD wire rating (See Page 18)
• One fully-charged automobile battery
• A common, slip joint pliers for loosening and tightening terminal nuts
TEST PROCEDURE:
1. Remove the plastic terminal covers and terminal nuts.
2. Identify the positive and negative terminals on the 12VDC battery
and identify the positive and negative terminals on the inverter.
3. Using the set of heavy-duty jumper cables, attach one red cable clamp
to the (+) terminal bolt and one black cable clamp on the (–) terminal bolt.
4. Connect the clamps on the other ends of the jumper cables to the
corresponding positive (+) and negative (–) terminals on the 12VDC
vehicle battery. There may be some minor sparking observed.
5. Turn the inverter power switch on.
6. Plug in a lamp with a 100 watt light bulb and switch the lamp on. If the lamp
works normally, the inverter is functioning properly and you can proceed to
a permanent installation or continue to use the inverter with low wattage
appliances. If the lamp does not light or does not work correctly:
A. Check all connections and tighten any loose connections.
B. Ensure that the source battery has adequate charge.
C. If steps A through B do not correct the problem, contact Vector
Customer Service Department toll-free (866) 584-5504, for assistance.
5.5 PERMANENT INSTALLATION
5.5.1 PREPARATION FOR PERMANENT INSTALLATION
(SEE PAGE 18 FOR SPECIFIC AWG CABLES FOR INVERTER MODELS)
For permanent installation to heavy-duty battery power you will need:
• Ring terminals to fit cable ends and stud terminals
• Hardware to connect two specified cables to the battery bank
• A specified single length of specific AWG cable multi-stranded,
flexible, insulated cable
• A specified amp low voltage fuse holder and fuse (slow blow type
or use a specified fuse or equivalent fuse holder
• Mounting screws, bolts and nuts for mounting the inverter and
fuse holder
• A drill for mounting the inverter and fuse holder
• Lead-tin solder, flux, propane torch and an igniter for the torch
• Wire stripper/cutter tool
• Battery connector for specified cable for battery connection
15
PRELIMINARY INSTALLATION NOTES:
The inverter has four slots in its mounting bracket that allow the unit to be fastened
against a bulkhead, floor, wall or other flat surface. Ideally, the mounting surface
should be cool to the touch. It is more electrically efficient to use longer AC wiring
than DC wiring, so install the inverter as close as possible to the 12VDC power source.
Vector inverters can be operated in any position, however, if it is to be mounted on
a wall, mount it horizontally so that indicators, switches, outlets and terminal blocks
on the front panel are visible and accessible.
1) If inverter is to be installed in a vehicle, Vector recommends that the inverter be
shock mounted to either the floor (in a clear, safe area) or on a secure flat surface.
2) Locate a convenient place to mount the inverter and fuse holder.
3) Perform a test routing of the proposed cable length, but don’t do any cutting at
this time. (FIGURE 7)
4) Be sure that the positive (+) and negative (-) cables to the battery DO NOT exceed 6 feet.
5) Using a specified AWG cable, reposition the inverter and fuse holder if necessary.
6) After you have practiced the above preliminary installation steps, proceed with
the “actual” inverter installation.
After you have selected an appropriate location for the inverter and fuse block,
proceed with the actual installation of the inverter.

Contact Vector Manufacturing for any further installation information or
questions. You can purchase fuses, fuse holders, specific cable or cable
battery connectors from your local electrical supplier or call Vector Technical
Support toll-free (866) 584-5504.
This procedure is for using locally purchased supplies. Make
appropriate changes to procedure if Vector Cable Set is purchased.
5.5.2 PERMANENT INSTALLATION PROCEDURES
The cables between the power source and inverter should be as shown in
FIGURE 7 (Page 13). Remove terminal cover and terminal nuts before starting
permanent installation.
Inverter DC cables and fuse installation are as follows:
1. Using tools and hardware, mount the inverter to a flat surface.
2. Mount the fuse holder to its mounting surface using appropriate hardware.
Ensure that mounting hardware does not touch any fuse holder or fuse con-
tacts. Ensure that fuse is removed from its holder.
3. Measure the cable twice before cutting the cable.
4. Cut one cable length to connect the negative (–) battery terminal and the
inverter’s negative terminal, leaving a little slack in the cable.
5. Cut another cable to connect the positive (+) battery terminal to one side of
fuse holder, leaving a little slack.
6. Cut the final cable to connect the other side of fuse holder to the positive (+)
terminal on the inverter back panel.
7. Strip the insulation of the three cables to 1-inch (2.45 cm) .
8. Crimp or sweat-solder the copper strands to ring terminals. For safety, do
this in an open space because it may require the use of a propane torch.
16
9. Crimp or clamp on a heavy-duty, battery-connection terminal to the other
end of the negative (–) and positive (+) cable. Connect the negative (–) bat-
tery terminal cable to the negative (–) battery terminal connector.
10. Ensure the inverter power switch is in the off position (see FIGURE 1).
11. Connect the ring terminal end of the negative (–) cable into the black stud marked
(–) on the inverter back panel and tighten the retaining nut.
12. Connect the battery connector to the negative (–) battery terminal.
13. Connect the ring terminal end of the positive (+) cable into the red stud
marked (+) on the inverter’s back panel (see FIGURE 2) and tighten the
retaining nut.
14. Connect the other end of the (+) positive cable to one terminal of the
heavy-duty fuse holder.
15. Connect the other conductor of the heavy-duty fuse holder to the positive (+)
battery terminal.
16. Connect an insulated wire (at least #12 AWG) between the chassis ground-
ing screw on the inverter’s case and a solid electrical ground to minimize
possible electrical noise generation in TVs and radios.
Do NOT connect this wire to the negative DC input terminal.
17. Ensure that all electrical connections are tight.
18. Ensure that the inverter’s on/of switch is OFF.
19. Insert the fuse into the fuse holder. (There may be some sparking.)
20. Turn “on” the inverter and apply a test load to the AC outlets.
21. Ensure the battery has an adequate charge. If voltage is low, the cables may
be too long or the gauge too light.
22. If steps 17 and 21 do not correct the problem, contact Vector Technical
Support Department toll-free (866) 584-5504, for professional direction.

8.0 TROUBLESHOOTING
8.1 COMMON PROBLEMS:
POWER TOOLS AND MICROWAVE OVENS WON’T START
Read the information panel on each power tool carefully to accurately determine
the tool’s input wattage. The wattage output is sufficient to operate most power
tools and microwave ovens, but remember, the power needed to start the power
tool may be as much as 2 to 6 times its continuous wattage requirements.
"BUZZING" SOUND IN AUDIO SYSTEMS AND/OR SNOW IN TVS
Inverters are shielded to minimize interference with TV signals. Ensure that the TV
antenna provides an adequate "snow free" signal and the antenna cable is high
quality and shielded without the inverter operating. The problem may not
be with the inverter. However, in some cases, some interference may be visible,
particularly with weak TV signals. Try the following corrective measures:
• Position the TV and antenna further away from the inverter, if it is the cause
of interference. Adjust the antenna, or use commercial cable hook-up (if possi-
ble) for best results
• Do not operate high-power appliances or tools when you are watching TV
• Make sure inverter's case is properly grounded as described in section 5.5.2

INVERTER SHUTS DOWN OR BATTERY FUSE OPENS
Inverter will continuously deliver rated watts (FIGURE 6) of AC power
continuously and will deliver rated peak watts ; after which, the inverter may
shut itself down, or the battery fuse will open, due to overload or excessive load
demand on start-up. Replace battery fuse, if opened. Allow the inverter to cool
for at least 15 minutes before attempting to start or run a high current draw
device. Reduce the load on the inverter to its maximum rated output power.
