Understanding the fan operation:
The fan on the unit is AC load and internal temperature activated. It will automatically turn on when
AC output power exceeds the pre-set values (~ 200W) and turn off when AC output power is reduced
to 150W. It will also automatically turn on when it senses the internal components have reached
approximately 80°C and turn off when temperature drops below 60°C.
Use of the Ignition Start Function on unit:
An ‘Ignition Start’ port is located on the Front AC Panel of the unit using a ¼” width spade terminal.
This port is used for turning the unit On and OFF using a +12V signal. An insulated female connector
is required to connect to the port.
Connecting to +12V will turn ON the unit and removing the +12V signal will turn OFF the unit.
Understanding the Warning and Shutdown Condition
•
Over Temperature Warning: Unit internal temperature is high. Unit requires better ventilation.
•
DC Over Voltage Warning: DC Input Voltage is high and close to the over-voltage shutdown limit.
Check the battery voltage.
