WARNING
Hazardous voltage.
Backfeed to the utility system can
cause property damage, severe
injury, or death.
If the generator set is used for
standby power, install an automatic
transfer switch to prevent inadvertent
interconnection
normal sources of supply.
The following sections cover electrical connections of
the automatic transfer switches and RBUS accessories,
including the programmable interface module (PIM), or
the load shed kit.
Note: Load shed kits are not available when combined
with the transfer switch supplied with models
8RESVL, 10RESVL, 12RESVL.
Generator Set
Note: Generator set terminal block (TB3) connections 3 and 4 are NOT USED with the Model RXT ATS.
1. Generator set terminal block TB3. See Figure 3-5 for location. Check the decal on the generator set for terminal block connections.
2. Connect one end of each cable shield to GROUND at the generator set.

1.10.1 Transfer Switch Connection

Connect the ATS or remote start/stop switch. Connect
the load leads from the generator set to the Emergency
source
lugs
on
communication leads through separate conduit from the
AC power and load leads. All connections must comply
with applicable state and local codes.
Note: Do not use the Kohlerr Model RRT transfer
switch with the RESV or RESVL generator set.
Communication connections for a Kohlerr
Model RXT transfer switch
One Model RXT transfer switch can be connected to the
generator set. See Figure 1-20. Use shielded,
twisted-pair communication cable to connect P10-1
through P10-4 on the transfer switch interface module to
the generator set terminal block connections A, B, PWR,
and COM.
The Model RXT transfer switch with the combined
interface/load management board requires one set of
RBUS connections to the generator set. However, the
combined board acts as two RBUS modules: one RXT
transfer switch and one load management device.
Note: Connections 3 and 4 on the generator set are not
used with the Model RXT transfer switch.
