Connect to the Ethernet cable in the customer
connection area of the generator set. See Figure 5-8.
Use an RJ45 inline coupler, provided with the OnCue
Plus kit, to connect the customer’s Ethernet cable to the
cable in the customer connection box.

5.5 Load Management Devices
Two optional load management devices are available
for use with single-phase generator sets and a model
RXT or RDT transfer switch:
 The optional Load Shed Kit mounts inside a Model
RDT or RXT transfer switch. Figure 5-9 shows the
load shed assembly.
 The combined interface/load management board is
available for the Model RXT transfer switch.
The devices provide 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.
Note: The load management devices are only
compatible with single-phase generator sets.
With a load management system, 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 load shed kit or combined interface/load
management board can be used to automatically
manage up to six residential loads:
 Up to four normally closed power relays can be
connected through normally open relay contacts on
the circuit board. See the load shed kit installation
instructions for relay specifications. Kohler Power
Relay Modules are recomended.
 Two relays are included on the load management
device to control two independent heating,
ventilation, and air conditioning (HVAC) loads.
Note: Connect only non-essential loads to the load
shed kit.
The load management device receives commands from
the RDC2 generator controller and energizes or
de-energizes the appropriate load relays to add or shed
non-critical loads according to their priority.
An adequate electrical supply is required for operation
of the power relays connected to the load shed kit.
Check the electrical requirements of the connected
equipment prior to installation to determine the wire size
and circuit protection required. Verify that
customer-provided equipment complies with applicable
local and national electrical codes.
