Operating in Shore Power Mode
Definition Shore power (pass-through) refers to the AC input power from a utility
grid, generator, or external AC source.
Shore power mode In shore power mode, the XS400 is connected to shore power and your
appliances are powered from the AC input power.
Transfer to invert
mode
The transfer to inverter power will occur if shore power is present, but
either the shore power voltage is too low (less than 85 volts AC) or too
high (greater than 140 volts AC). In this case, the transfer from shore
power to inverter power prevents damage to your appliances.

You cannot use the S400 Remote Switch to control the XS400 when it is
operating in shore power mode.

Important: The XS400 transfers the appliances to shore power
whenever shore power is connected, regardless of the position of the
On/Standby switches.
