Load Control Module (Lcm) - Kohler 14RESA Installation Manual

1.12.2 Load Control Module (LCM)

The optional Load Control Module (LCM) is available for
single-phase generator sets only. The LCM provides
an automatic load management system to comply with
Section 702.5 of NEC 2008. The installer is responsible
for ensuring that the power system installation complies
with all applicable state and local codes.
With the Load Control Module (LCM), less critical
appliances can be powered by the generator set when
the more important appliances are not running, allowing
the use of a smaller generator set than would be needed
to run all of the building's electrical equipment at the
same time.
The LCM receives commands from the RDC2 or DC2
generator controller and energizes or de-energizes the
appropriate load relays to add or shed non-critical loads
according to their priority.
Note: Connect only non-essential loads to the load
control module.
The load control module automatically manages up to
six residential loads:
Four power relays are provided for management of
D
non-essential secondary loads. 120 VAC power must
be provided for operation of the power relays.
Two relays are available to control two independent
D
air conditioner loads.
The LCM is available with either a prewired harness for
load relay connection, or a terminal block. The prewired
harness requires installation of the LCM within
0.6 meters (2 feet) of the distribution panel. The load
control module with the optional wire harness is shown
in Figure 1-32. If the harness is not used, connect to the
terminal blocks inside the LCM enclosure. Figure 1-33
shows the load control module without the optional
harness.
Refer to TT-1574, provided with the LCM, for installation
and connection instructions.
