• If you are using the power inverter to
operate battery charger, monitor the
temperature of the battery charger
for about 10 minutes. If the battery
charger becomes abnormally warm,
disconnect it from the inverter im-
mediately.
• If you are powering the inverter with
an automobile or marine battery, start
the engine every 30 to 45 minutes
and let it run for about 10 minutes to
recharge the battery.
• If you hear a continuous alarm or
automatic shut down, turn the inverter
OFF immediately. Do not restart the
inverter until the source of the problem
has been identified and corrected.
• Disconnect the inverter when not in
use in order to avoid battery drain.

ProBleM: low or no output
Voltage
Reason/Solution
1. Poor contact at terminals.
Unhook and rehook the 12-volt
connections.
2. Using incorrect type of voltmeter
to test output voltage.
Use a true RMS reading meter.
ProBleM: red leD on
Reason/Solution
1. Battery voltage below 11 volts.
Recharge or replace battery.
2. equipment being operated is
drawing too much power.
Use a higher capacity inverter or do
not use this equipment.
3. Inverter is too hot (thermal shut
down mode).
Allow inverter to cool. Check for
adequate ventilation. Reduce
the load on the inverter to rated
continuous power output.
ProBleM: Audible Alarm on All
The Time
Reason/Solution
1. Input voltage below 11 volts.
Recharge or replace battery to
maintain adequate power input.
2. Poor or weak battery condition.
Recharge or replace battery.
ProBleM: Device Does not Work
Reason/Solution
1. Device does not turn on.
Try turning the inverter ON, then
OFF, then ON again. Contact
the device manufacture for start
up surge and/or if the device is
compatible with a modified sine
wave. An inverter producing a larger
power out-put may be required.
2. Inverter may be defective.
