Operating the XS400
975-0054-01-01 3–3
Operating the XS400
The XS400 operates in either invert mode or shore power mode.
Invert mode In invert mode, the XS400 powers your appliances from the battery. See
“Operating in Invert Mode” on page 3–5.
Shore power mode In shore power mode, the XS400 is connected to shore power and your
appliances are powered from the AC input power. See “Operating in
Shore Power Mode” on page 3–7.
Shore power (pass-through) refers to the AC input power from a utility
grid, generator or external AC source.
Turning the XS400 to On
or to Standby
The On/Standby switch on the XS400 turns the inverter to On () or to
Standby ( ) when operating in invert mode.
If you have installed the S400 Remote Switch, you can also use the
remote switch to turn the XS400 to On
() or to Standby ( ). See “Using
the S400 Remote Switch” on page 3–4.
The On/Standby switch on the XS400 or the S400 Remote Switch is also
used to reset the inverter after a Fault condition. See “Resetting After a
Fault or Shutdown” on page 3–9.
Turning the XS400 to Standby When Not in Use
If you won’t be using the XS400 for an extended period of time, turn the
inverter’s On/Standby switch to the Standby ( ) position. Turning the
switch to Standby ensures that the XS400 draws no current from the
battery.
If you are disconnected from shore power with the XS400 On/Standby
switch in the On
() position and the S400 Remote Switch in the Standby
( ) position, the XS400 draws very little current (about 1 mA) from the
battery.
WARNING: Shock hazard
When the On/Standby switch is in the Standby ( ) position and
the XS400 is connected to shore power, AC voltage will be
present at the output of the inverter.
Important: The XS400 operates normally without the S400 Remote
Switch installed.
