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).
Fault Protection and Troubleshooting Guide
INVERTER POWER SWITCH TURNED ON
Trouble/Indication Possible Cause Suggested Remedy
No AC output — DC input is below 10 volts Recharge or replace battery.
red LED lit
Excessive appliance load Turn unit off. Reduce the load,
— thermal shutdown wait for the inverter to cool
down, then turn the unit on
again.
No AC output — Fuse(s) open Check DC input — fuse(s) in
green LED not lit vehicle. Replace the fuse with
one of the same type and rating
if necessary.
Low battery alarm Low battery voltage Recharge battery. Remove
sounds continuously load from the inverter while
recharging battery.
Bad connection or wiring Tighten all DC connections.
Motorized power tool Excessive start-up load If appliance does not start,
will not start appliance is drawing
excessive voltage and
will not work with inverter.
Motorized power tool Purely inductive load Make the load not purely
does not operate at inductive. Operate an
correct speed incandescent lamp at the
same time as motor.
Television/radio Snow in picture, Keep inverter and antenna
interference “buzzing” sound distant from each other. Use
shielded antenna. Connect
antenna to amplifier.

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.
Notes on Using the Remote Control (sold separately)
For ease of use, Vector offers (as a separate item) a Remote Control specifically
designed for this line of MAXX SST inverters. The inverter ON/OFF Switch must be
in the OFF position when connecting the Remote Control to the unit or the Remote
Control will not operate. Once the unit has been turned ON using the Remote Control,
inverter operation will continue to be controlled through the Remote Control. Turn the
inverter OFF before disconnecting the Remote Control.
For more information about attaching and using the Remote Control, please refer to
the Remote Control User’s Manual.
CARE AND MAINTENANCE
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.
Preventive Maintenance
Inverters require minimal maintenance. For optimum performance, the manufacturer
recomments periodically performing the following preventive maintenance.
1. Turn OFF the inverter using the front panel ON/OFF Power Switch.
2. Remove the DC power fuse.
3. Check and tighten all electrical connections, including the ground.
4. Using a non-metallic vacuum cleaner hose, vacuum the air slots and fan area.
5. Clean the outside of the unit using a damp (not wet) cloth.
6. Wipe unit surfaces thoroughly with a dry cloth.
7. Re-insert the fuse and resume operation.
