Monthly testing
Once a month, with either AC shorepower or inverter power
present, press the test button on the GFCI receptacle. The
reset button should pop out. Push it to reset the GFCI, and
continue normal operation. This should be completed on a
monthly basis.
If the reset button does not pop out, the GFCI may have
failed. Disconnect AC and DC power to the unit and have a
qualified service person look at it.
Alternate AC source
An AC input cord is provided at the back of the unit allowing
for alternate source AC power. Plug the input cord on the
back of the HI400 into a shorepower receptacle. The load can
be run from the alternate source when it is present.
When the shorepower source is not present, the internal
transfer relay will automatically transfer the load to inverter
power. This transfer relay functions whether the power
switch is in the on or off position.
Ignition lockout
The inverter automatically shuts off when the ignition
lockout is engaged. This occurs when the power switch is in
the On position and a 12 volt signal (not to exceed 16 Vdc) is
applied to the ignition lockout wire. Refer to page 18 for
details.
Low battery condition
When the low battery red LED light illuminates, the battery
voltage has dropped below 10.5 Vdc. When the battery
voltage drops below 10.0 Vdc, the inverter turns off to
prevent further discharging of the battery by the HI400.
