• 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.
