975-0054-01-01 2–23
Step 12: Testing Your Installation
There are two tests to be performed. The first test verifies that the XS400
operates in invert mode. The second test verifies that the XS400 operates
in shore power mode.
When you are ready to test your installation and operate the XS400, close
the DC fuse and Disconnect or the DC circuit breaker to supply DC power
to the XS400.
Testing in Invert Mode
To test the XS400 in invert mode:
1. Ensure that shore power is disconnected.
2. Turn the inverter’s On/Standby switch to the On ( ) position. Turn the
On/Standby switch on the S400 Remote Switch to the On
() position.
The green Inverter On indicator illuminates.
3. Plug an appliance of 400 watts or less into one of the GFCI outlets.
4. Turn the appliance on to verify that it operates.
5. If the appliance operates, your installation is successful.
6. If the red Fault light illuminates, see “Troubleshooting” on page 4–1.
Testing in Shore Power Mode
To test the XS400 in shore power mode:
1. Connect to the shore power source.
The XS400 transfers the appliances to shore power with the
On/Standby switch of the inverter or the S400 Remote Switch in
either the On ( ) or Standby ( ) position. The green AC Input light
illuminates.
2. Plug an appliance of 400 watts or less into one of the GFCI outlets.
3. Turn the appliance on to verify that it operates.
WARNING: Shock hazard
The On/Standby switches on the XS400 and the S400 Remote
Switch do not disconnect DC or AC input power to the XS400.
Note: Shore power (pass-through) refers to the AC input power from a
utility grid, generator or external AC source
