RBUS communication connections for a Kohler
®
Model RXT transfer switch
One Model RXT transfer switch can be connected to the generator set. See Figure 13. Use shielded, twisted-pair 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. See Communication Cable Specifications Section for communication cable recommendations and maximum cable
length.
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
