IMPORTANT SAFETY INSTRUCTIONS
WARNINGS
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, EXPLOSION OR INJURY:
• NEVER connect to AC distribution wiring.
• Remove appliance plug from outlet strip or turn off inverter before working on the
appliance. Multiple outlet power strips with switches and circuit breakers only
interrupt power to the "hot" receptacle terminals. The "neutral" terminals remain
powered with respect to the "ground" terminals.
• NOT approved for ignition protected areas. Do not make any electrical connections
or disconnections in areas designated as IGNITION PROTECTED.
• This equipment employs components that tend to produce arcs or sparks. DO NOT
install in compartments containing batteries or flammable materials.
• Use this unit in properly ventilated areas ONLY.
• Do not open — there are no user-serviceable parts inside.
• Do not insert foreign objects into the outlets.
• Do not expose the unit to liquids, including water, rain or snow.
• This is not a toy — keep away from children.
CAUTIONS
• Always inspect battery supply connections and cables to ensure they are tight and that cable insulation
is not damaged.
• Do not use with positive ground electrical systems*. Reverse polarity connection will result in a blown
fuse and may cause permanent damage to the inverter and will void warranty.
*The majority of modern automobiles, RVs, trucks and boats are negative ground.
• Grounding the Neutral will cause the inverter to shut down. Do not operate this inverter if it is wet. Do
not install in engine compartment — install in a well ventilated area.
• This inverter has not been not tested for use with medical devices.
• Do not attempt to install or operate this unit while operating a motor vehicle.
APPLIANCE CAUTIONS
NEVER plug small appliances directly into the inverter outlets to recharge nickel-cadmium batteries.
Always use the charger provided with the 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.
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 toothbrushes that can
be plugged directly into an AC receptacle to recharge.
2. Battery chargers that 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.
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.
Important Cable Information
Substantial power loss and reduced battery operating time results from inverters installed with cables that
are not able to supply full power. Symptoms of low battery power can result from cables that are either
excessively long or an insufficient gauge. Marine installations are also subjected to vibration and stresses
that exceed those of other mobile installations. Therefore, the installer/operator should be especially
aware of the requirements to maintain secure, tight, water-resistant electrical connections and to provide
for strain relief for DC cables and appliance wiring. Cable insulation must be the appropriate type for
the environment.

INTRODUCTION
Thank you for purchasing a Vector MAXX SST™ Portside Power Inverter.
Please read this guide carefully before use to ensure optimum performance and to
avoid damage to this product.
This Power Inverter is configured with the latest Soft Start Technology (SST) and
supplies continuous power in the form of 120 volt AC outlets to run most household
or electronic appliances. Before introduction of SST, high start-up currents from large
inductive loads could shut down an inverter. SST improves inverter operation by:
• Gradual voltage ramp-up during inverter start-up, eliminating failed cold starts
under load.
• Output that momentarily dips in voltage and quickly recovers to allow large
motorized loads to start, eliminating most shutdowns from momentary overloads.
• A new technology that cools the power transistors more efficiently, and, combined
with Soft Start, dramatically increases reliability and life of the product.
Added safety features include automatic shutdown and a low battery alarm to prevent
damage to your 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 vehicle 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.
Modified Sine Wave and Sine Wave Comparison
PRINCIPLE OF OPERATION
APPLIANCE POWER CONSUMPTION
The MAXX SST™ Portside Power Inverter converts 12 volt DC (direct current) from a
vehicle battery or other 12 volt DC power source to standard 120 volt AC (alternating
current) household power.
It converts power in two stages (see the diagram below). In the first stage, the inverter
raises the 12 volt DC input to 145 volts DC. This inverter uses high-frequency
conversion techniques that replace bulky and heavy transformers found in older
inverters. In the second (output) stage, the inverter converts the 145 volt DC to
110/120 volt AC using multiple banks of metal-oxide semiconductor field-effect
transistors (MOSFETs). The unit’s solid-state circuitry ensures excellent overload
protection and the ability to operate reactive loads such as those found in inductive
motors. In this stage, the inverter functions as a high-power bipolar switch, alternately
applying opposite polarity to the AC outlet HOT and NEUTRAL terminals.
MAXX SST™ Portside Power Inverters are ideal for powering:
• Lights
• TVs and TV/DVD (VCR) combinations units
• Radio receivers/transceivers and stereo systems
• Computers and peripheral equipment
• Refrigerator/freezers
• Small microwave ovens
• Household appliances
• Dry and/or wet/dry vacuums
• Heavy duty power tools & chargers
• Sump pumps, motors and other electric-powered equipment

The Power Inverter Output Waveform
The AC output waveform of the Power Inverter is known as “modified sine wave.” It
is a waveform that has characteristics similar to the sine wave shape of utility power.
This type of waveform is suitable for most AC loads, including linear and switching
power supplies used in electronic equipment, transformers, and motors.
The modified sine wave produced by the Power Inverter has an RMS (root mean
square) voltage of 115 volts, which is the same as standard household power. Most
AC voltmeters (both digital and analog) are sensitive to the average value of the
waveform rather than the RMS value. They are calibrated for RMS voltage under the
assumption that the waveform measured will be a pure sine wave. These meters will
not read the RMS voltage of a modified sine wave correctly. They will read about 20
to 30 volts low when measuring the output of the inverter. For accurate measurement
of the output voltage of this unit, use a true RMS reading voltmeter such as a Fluke
179, Fluke 79 III series, Beckman 4410 or Triplett 4200.

110/120V AC
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 shutdown and
possible damage to the inverter, avoid exceeding the wattage rating of this unit. To
obtain a rough estimate of the current (in amperes) the power source must deliver
where the power consumption of the tool or device is given in watts AC, simply divide
the power consumption of the load by 110.
Example: If a load is rated at 200 watts AC, the power source must be able to deliver:
200 divided by 110 = 2 amperes.
The inverter has built-in overload protection so that if you do exceed the inverter’s
output capacity continuously, the unit 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 then ON again. The ON/OFF Switch is
located on the unit’s Front Panel (see page 2).
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.
CAUTIONS
Ensure that 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 start-up wattage
for inductive loads does not exceed peak watts for more than a second.
Appliances such as microwave ovens will normally 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.

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. For continuous use at maximum output, the
MAXX SST™ inverter must be connected to a DC power supply capable of
providing at least 1/10th of the inverter’s continuous wattage rating.
The inverter will operate most AC loads within its power rating. Some induction
motors used in refrigerators, freezers, pumps and other motor-operated equipment,
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 within 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 the
battery connections are tight and the battery (or batteries) is (are) fully-charged. If the
6
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).
CAUTION
Rechargeable Devices
Certain rechargeable devices do not operate well from a modified sine
wave inverter. They only operate properly from a standard household
outlet, which provides a pure sine wave. Therefore, the manufacturer
recommends that these types of devices be operated from a standard
household outlet only, not from the inverter.
This problem does not occur with most battery-operated equipment.
Most of these devices use a separate charger or transformer that is
plugged into an AC receptacle. This inverter is easily capable of
running most chargers and transformers.
OPERATING INSTRUCTIONS
Power Source Requirements
The inverter will operate from input voltages between 10.5 and 15.5 volts DC. 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 volts DC. 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.
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 tested. If an overload
is detected, the inverters will simply shut down until the overload situation is corrected.
Use the front panel switch to turn OFF the inverter, then ON, to reset the inverter.
CAUTIONS
Exceeding recommended voltage limits will void manufacturer’s
warranty.
NEVER try to use the inverter with any 12 volt DC power source
that uses a POSITIVE ground. (Most vehicles and boats use negative
ground systems.)
The 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 in the following “Battery Wiring”
diagram.

fuse be added as close as possible to the power source (battery) positive
terminal. The fuse amperage size must be appropriate 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. See “Specifications” on page 16.
Determining Battery Size
To determine the minimum battery size you will need to operate appliances from
MAXX SST™ inverters, 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.
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.
Keep in mind that some appliances are not drawing the same power continuously.
For example, a typical home-use coffee maker draws 500 watts during brew time
(approx. 5 minutes), but maintains the pot temperature at only about 100 watts.
Typical use of a microwave is only for a few minutes, sometimes at low power.
Runtime
The following graph is a set of curves that show how appliance load, in watts or
in amperes, affects runtime. 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,
200 Ah and 400 Ah capacities. These large capacity batteries clearly 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.

For example, as shown in the above graph, using a 400 A/h 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.
Protective Features
LOW BATTERY ALARM
An audible alarm will sound when the 12 volt DC power supply voltage drops below
10.5 volts DC. This indicates that the battery needs to be charged or there is an
excessive voltage drop between the battery power source and the inverter.
Notes: It is normal for the alarm to sound when the inverter is being connected to,
or disconnected from, a 12 volt DC power source. This does not indicate a
problem. However, if this alarm sounds continuously, discontinue inverter
operation and charge the battery before resuming operation. If the voltage
drops to 10.0 volts DC, the inverter will automatically shut down.
If the low voltage alarm sounds when the battery is fully charged (refer to
the “Fault Protection and Troubleshooting Guide” on pages 15).
CIRCUIT PROTECTION
The inverter has electronic circuit protection against overload or short circuit
conditions.
CAUTION
If turning the ON/OFF Switch OFF then ON again does not reset the
inverter, DO NOT ATTEMPT TO OPEN THE INVERTER. Opening the
inverter for any reason will void the warranty. The unit must
be returned to Vector Manufacturing for testing and repair by
professional factory technicians.

INSTALLATION
MAXX SST Portside Power Inverters will provide you with continuous electrical power
when powered by a 12 volt DC source, such as a vehicle battery or a multiple battery
configuration (see the diagram under “Battery Configuration,” page 8). This manual
does not describe all of the possible configurations.
™
Operating Environment
Do not locate inverters in an area, room or compartment where explosives or
flammable fumes might be present, such as engine rooms, engine compartments, and
boats or small, unvented battery compartments.
To avoid possible dangerous conditions, the inverters must be located where:
1. The unit is well-ventilated and dry, away from heat sources, such as dry engine
exhaust and other heat-producing devices;
2. Air temperature is between 30°F (–1°C), non-condensing, and 105° 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;
6. The unit is located so that hinged covers, access plates and all inverter controls
(switches, outlets and indicators) are readily accessible;
7. The unit is NOT installed directly over batteries — explosive gasses can ignite
and corrosive fumes can damage inverter components;
8. The unit is protected from falling objects, spray or dripping fluids;
9. Overcurrent protection is installed in the DC input circuit — this can be either
fuses or circuit breakers.
10. A means of achieving strain relief is installed within six inches (6") of the inverter
enclosure.
Never connect the chassis 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 wattage rating.
• NEVER place items on or over the inverter during operation
Inverters generate heat during operation and must be placed where cool air can
circulate to the internal fan, and hot 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 cables (see the diagram on page 8) are not supplied, but will be required to allow
for full power operation and to provide flexibility in positioning the inverter.
Marine Applications
In addition to the above recommendations and all cautions and warnings listed in the
Important Safety Instructions at the beginning of this User’s Manual, observe the
following 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.
10
Only connect the inverter’s DC input to existing wiring (which must be approved for
marine use) at the appropriate gauge, cable and length (see the “Specifications”
section, page 16). For cable lengths exceeding 6 feet from inverter to batteries, call
Vector for additional installation information. The cable, fuse holder and fuse (not
supplied) can be purchased at an electrical supply company. The fuse holder and fuse
are a specified amperage rating (see Specifications, page 16). Call Vector Technical
Support at (954) 584-4446 or toll-free at (866) 584-5504 with any questions.
Inverters must be securely fastened to bulkheads, floors, ceilings or other vessel
structural parts. They should be mounted horizontally so the fan area is not blocked.
When mounted, the base of the inverter must be at least two feet above normal bilge
water, and protected so it is not subject to bilge splash.
Inverters are NOT IGNITION-PROTECTED and should NEVER be installed in engine
rooms of gasoline-powered boats.
Installation Procedures
When wiring the inverter to a 12 volt DC power source, ensure that polarity is correct.
Reversed polarity will blow a fuse and may cause permanent damage to the inverter.
Review diagrams on page 2, if necessary, to identify the location of the DC terminals.
Note: The manufacturer’s warranty does NOT cover damage due to reversed polarity.
Quick Operational Test or Emergency Use
You will need:
• A heavy-duty jumper cable set of the specified AWG wire rating (see the
“Specifications” section, page 16)
• A fully-charged automobile battery
• A common slip joint plier for loosening and tightening terminal nuts
PROCEDURE
1. Unscrew nuts in input terminal block.
2. Identify the POSITIVE and NEGATIVE terminals on the 12 volt DC battery (or
other 12 volt DC power source) and identify the POSITIVE and NEGATIVE
terminals on the inverter.
3. Using a set of heavy-duty jumper cables, attach the red cable to the inverter’s
POSITIVE (+) terminal and the black cable to the inverter’s NEGATIVE (–)
terminal.
4. Connect the clamps on the other ends of the jumper cables to the corresponding
POSITIVE (+) and NEGATIVE (–) terminals on the 12 volt DC vehicle battery (or
other 12 volt DC power source). There may be some minor sparking.
5. Turn the inverter ON/OFF 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 that may be loose.
B. Ensure that the source battery has adequate charge.
C. If steps A and B do not correct the problem, contact Vector Technical Support,
toll-free, at (866) 584-5504, for assistance.

Permanent Installation
For permanent installation to heavy-duty battery power you will need:
• Two cables (as indicated in the “Specifications” section on page 16)
• Terminals to fit cable ends and stud terminals to inverter
• Hardware and battery connector to connect cables to the battery bank
• A single length of AWG cable multi-stranded, flexible, insulated cable (as indicated
in the “Specifications” section on page 16) for chasis ground connection
• A holder and fuse (see “Specifications” on page16)
• 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/cutting tool
PRELIMINARY STEPS
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 efficient to use longer AC wiring than DC
wiring, so install the inverter as close as possible to the 12 volt DC power source.
The inverter should be operated in horizontal position; 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, it is recommended that the unit 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 (refer to the diagram on page 8 under “Battery Configuration”).
4. Be sure that the POSITIVE (+) and NEGATIVE (–) cables to the battery do not
exceed six feet.
5. Using an appropriate AWG cable (see “Specifications” on page 16), reposition
the inverter and fuse holder if necessary.
6. Proceed with the actual inverter installation.
You can purchase fuses, fuse holders, specific cable or cable battery
connectors from your local electrical supplier. These are not supplied
with this unit. Contact the manufacturer for any further installation
information or questions, toll-free, at (866) 584-5504.
Note: The following procedures are for using locally purchased supplies. If a Vector
Cable Set is used, follow the directions included with that set.
PERMANENT INSTALLATION PROCEDURE
The cables between the power source and inverter should be set up as illustrated in
the diagram on page 8. Also refer to the “Control and Function Guide” on page 2.
Unscrew terminal nuts before beginning permanent installation. Proceed with DC cable
and fuse installation as follows:
1. Ensure the inverter’s ON/OFF Power Switch is in the OFF position.
2. Using tools and hardware, mount the inverter to a flat surface.
3. Mount the fuse holder to its mounting surface using appropriate hardware. Ensure
that mounting hardware does not touch any fuse holder or fuse contacts. Ensure
that fuse is removed from its holder.
12
4. Measure the cable twice before cutting the cable.
5. Cut one cable length to connect the NEGATIVE (–) battery terminal to the
inverter’s NEGATIVE terminal, leaving a little slack in the cable.
6. Cut another cable to connect the POSITIVE (+) battery terminal to one side of fuse
holder, leaving a little slack.
7. Cut the final cable to connect the other side of fuse holder to the inverter’s
POSITIVE (+) terminal.
8. Strip the end insulation of all three cables to 1-inch (2.45 cm).
9. 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.
10. Crimp or clamp on a heavy-duty, battery connection terminal to the other end of
the NEGATIVE (–) and POSITIVE (+) cable. Connect the NEGATIVE (–) battery
terminal cable to the NEGATIVE (–) battery terminal connector.
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 back panel and tighten the retaining nut.
14. Connect the otehr end of the POSITIVE (+) cable to one terminal of hte 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 grounding
screw on the inverter’s case and a solid electrical ground to minimize possible
electrical noise in TVs and radios. Do not connect this wire to the
negative DC input terminal.
17. Ensure that all electrical connections have been tightened.
18. Insert the fuse into the fuse holder. There may be some sparking.
19. Ensure the 12 volt DC power source has an adequate charge.
21. Turn the inverter ON and apply a test load to the 120 volt AC outlets.
If, after following all of the above steps, the inverter does not perform properly, the
source voltage may be too low or the cables may be too long (or the gauge too light).
Having checked and, if necessary, corrected these conditions, contact Vector Technical
Support, toll-free, at (866) 584-5504 for assistance if problems persist.
Connection To Load
The Power Inverter is equipped with standard North American three-prong type
outlets. Plug the cord from the equipment you wish to operate into the AC outlet(s).
Make sure the combined load requirement of your equipment does not exceed
maximum continuous power.
The Power Inverter is engineered to be connected directly to standard electrical and
electronic equipment in the manner described above. Do not connect the Power
Inverter to household or RV AC distribution wiring. Do not connect the Power Inverter
to any AC load circuit in which the neutral conductor is connected to ground (earth)
or to the NEGATIVE of the DC (battery) source.
WARNING
Do not connect to AC distribution wiring!

Operating Tips
For best operating results, the inverter should be placed on a stable, flat surface. The
inverter should only be used in locations that meet the following criteria:
DRY — Do not allow water or other liquids to come into contact with the inverter.
COOL — Surrounding air temperature should be between –1°C and 40°C (30°F and
105°F). Keep the inverter away from direct sunlight, when possible.
WELL-VENTILATED — Keep the area surrounding the inverter clear to ensure free air
circulation around the unit. Do not place items on or over the inverter during
operation. The unit will shut down if the internal temperature gets too hot.
SAFE — Do not use the inverter near flammable materials or in any locations that may
accumulate flammable fumes or gases. This is an electrical appliance that can briefly
spark when electrical connections are made or broken.
CAUTION
Rechargeable Devices
Certain rechargeable devices do not operate well from a modified sine
wave inverter. They only operate properly from a standard household
outlet, which provides a pure sine wave. Therefore, the manufacturer
recommends that these types of devices be operated from a standard
household outlet only, not from the inverter.
This problem does not occur with most battery-operated equipment.
Most of these devices use a separate charger or transformer that is
plugged into an AC receptacle. The Power Inverter is easily capable of
running most chargers and transformers.
CARE AND MAINTENANCE
TROUBLESHOOTING
Common Audio/Visual Problems
“Buzzing” sound in audio systems
Some inexpensive stereo systems and “boom boxes” emit a buzzing sound from their
speakers when operated from the Power Inverter. This occurs because the power
supply in the electronic device does not adequately filter the modified sine wave
produced by the inverter. The only solution to this problem is to use a higher quality
sound system that incorporates a higher quality power amplified supply.
Television Interference
The Inverter is shielded to minimize interference with TV signals. However, in some
instances, some interference may still be visible, particularly with weak TV signals. Try
the following corrective measures:
• Position the inverter as far as possible from the television, the antenna and the
antenna cables. Use an extension cable, if necessary.
• Adjust the orientation of the inverter, the antenna cables and the TV power cord to
minimize interference.
• Make sure the antenna feeding the television provides an adequate (“snow free”)
signal and that high quality, shielded antenna cable is used.
• Do not use the inverter to operate high-power appliances or tools at the same time
you are using it to operate the TV.
• Make sure the inverter’s case is properly grounded (see “Permanent Installation
Procedure” on page 12).
Resetting the Unit
To reset the inverter, turn the ON/OFF Power Switch to the “OFF” position, then back
“ON” agin.
Storage
1. Ideal storage temperature range is 50-68°F (10-20°C).
2. Store and use the inverter in a cool, dry place with adequate ventilation.
3. Avoid locations that are exposed to heating units, radiators, direct sunlight or
excessive humidity or dampness.
Fuse Replacement
This inverter is equipped with multiple internal fuses. Normally, these fuses will not
“blow” unless there is a serious problem inside the unit. Internal fuses are
replaceable; however, only trained personnel should attempt fuse
replacement. If the unit is damaged during fuse replacement, the warranty may be
voided. The manufacturer recommends contacting Technical Support, toll-free, at
(866) 584-5504.
