1. Operating the Inverter, continued

Fault or Alarm Conditions

The inverter monitors the AC Shore Power, the batteries and itself. Whenever a

condition occurs that is outside the normal operating parameters, the inverter will

take the necessary steps to protect your appliances, batteries or itself from damage.

Low Battery

Whenever the battery voltage reaches a low level, the inverter will initiate Low

Battery Cutoff (LBCO) which automatically shuts the inverter down, along with all

connected loads, to protect the batteries from over-discharge damage. The

inverters LED turns OFF to indicate the fault condition.

High Battery

As the inverter is charging, it constantly monitors the batteries. In the event the

battery voltage approaches too high of level, it automatically turns off the battery

charger to protect the batteries from damage. The inverters LED turns OFF to

indicate the fault condition.

NOTE: High battery voltage may be caused by excessive voltage from the alternator,

solar panels or other external charging sources.

Overload

During inverter and AC Shore Power operation, the inverter monitors the AC and

DC circuits. In the event of a short-circuit or overload condition, the inverter will shut

down. The inverters LED turns OFF to indicate the fault condition.

Overtemperature

During inverter operation, if the inverter becomes overheated, it will shut down to

protect itself from damage. The inverters LED turns OFF to indicate the fault condi-

tion.
