3.7.2.1 Voltage Select Inputs
You can choose a voltage configuration by setting one or two of the configurable
switched inputs to Volt Select 1 and Volt Select 2. This allows the GSC400 to
automatically re-configure its voltage display as well as warning/shutdown trip
points relating to AC voltages and currents. This is useful for mobile generators
where the voltage selections can be selected via a CAM switch.
Warning: The Voltage Select Inputs override the Voltage Group parameter.

If Digital Input Pin A, B, C or D is used, then ACTIVE is defined as a switched
to +BAT connection. If Digital Input Pin E, F, G or H is used, then ACTIVE is
defined as a switched to GND connection.
NOTE: If only a single AC Group Sel function is selected, then the remaining
unassigned AC Group Sel is equivalent to an “Open Circuit” in the above table.
