When installing a multiple unit system, every setting on the Multi Unit Config
menu (except for Dev Name) must be configured for each of the two Conext SW
units in the system. The settings should be configured in the following order: Dev
Number then Invtr Mode.
AC In setting The Conext SW accepts only a single AC source - either from the grid or from a
generator. In a power system where the Conext SW is solely connected to the
grid and an AGS is neither present nor required, the AC In setting can be either
Gen1 or Grid1. Therefore, the default value of Gen1 need not be changed.
In a situation where the AC source is a generator and the AGS is being used to
start the generator to produce AC power, the AC In setting must be set to Gen1.
Therefore, the default value of Gen1 must remain unchanged.
In a power system where the two AC sources are available but only one AC
source can be used, an external transfer switch becomes necessary. When an
external transfer switch is used and an AGS (with a B+ signal connection) is also
present, change the AC In setting to Grid1.
Invtr Mode For this to operate, one
Conext SW must be
configured to Master
and the other as Slave,
otherwise a system-wide
fault is asserted.
Master Master,

AC In For identifying the type
of AC source when two
power sources are
