Installing the XS400
Step 12: Testing Your Installation
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.
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
