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 RS400 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.
S400 Remote
Switch
You cannot use the optional S400 Remote Switch to control the RS400
when it is operating in shore power mode.
To operate in shore power mode:
1. Connect the RS400 to shore power.
The AC Input light on the RS400 illuminates. The On/Standby switch
on both the S400 Remote Switch and the RS400 can be either On
()
or in Standby ( ) position.
2. Operate your appliances.
Important: The RS400 transfers the appliances to shore power
whenever shore power is connected, regardless of the position of the On/
Standby switches.
