1 Installation Procedure
1. Press the OFF button on the generator set
controller.
2. Disconnect the utility power to the generator set.
3. Disconnect the generator set engine starting
battery(ies), negative (--) lead first.
4. Remove the LCM enclosure cover. Cover the
internal components to protect them from metal
chips and debris.
Note: Use separate conduit for the controller
communication
leads and the load
connection wiring.
Note: Low voltage wiring must enter the enclosure
above
the power relays to ensure
separation of circuits per NEC
requirements. Route the low voltage wiring
to avoid contact with: 1) line voltage field
wiring to the relays; 2) live parts of the relays;
and 3) and all insulated lead wires to the
relays – contacts and coil. See Figure 28.
5. Mark the location of an opening in the side of the
enclosure for the communication leads. The
opening must be above the power relays. See
Figure 28. Cut an opening in the enclosure for the
generator set communication leads.
Note: For outdoor installations, use watertight
conduit hubs.
6. If the LCM is not equipped with a pre-wired
harness, use the knockout provided in the bottom
of the enclosure for the load leads.
7. Mount the load control module (LCM) enclosure on
the wall near the main distribution panel. See the
dimension drawing in Figure 28 for the mounting
hole size and locations.
Note: The mounting holes have gaskets to seal
out moisture.
Use washers with the
mounting screws to protect the gaskets.
8. Install the current transformer (CT) on the
emergency source lines. Installation inside the
transfer switch enclosure is recommended.
Note: Be sure to route the leads through the
current transformer from opposite sides as
shown in Figure 5. The leads must cross as
they pass through the transformer.
