Installation Guide

TP-7091 2/2126 Section 3 Electrical
6. For connection of optional accessories, including
the programmable interface module (PIM), and/or
a load shed kit, see Section 3.3.2.
Note: Connect the shield on the outside of the
accessory communication cable to the
ground lug near the terminal block (item 6 in
Figure 3-3).
7. If the OnCue Plus Generator Management
System will be used with the generator set, run
category 5E network cable from the generator set
to the customer’s router or modem.
a. Route the network cable with other low-voltage
signal wiring (for example, the RBUS
communication leads or engine start leads to
the transfer switch), in separate conduit from
the AC load leads. If the network cable is longer
than 100 meters (328 ft.), use a repeater or
switch.
b. Use an RJ45 inline coupler to connect the
Ethernet cable to the cable in the customer
connection box. See Figure 3-3. The inline
coupler is included with the OnCue Plus kit.
As an alternative, the Ethernet cable can be
connected directly to Ethernet connector P6 on
the back of the RDC2 controller.
8. When connections are complete, replace the cover
plate.
3.1.5 AC Power Supply
The installer must connect AC power for the battery
charger (which is integral to the RDC2 controller) and
the optional accessories shown in Figure 3-4. The
power source must comply with state and local codes.
The power to the battery charger and accessories must
be backed up by the generator so that power is available
at all times.
Be sure to disconnect power at the distribution panel
before making the connections. Connect power leads to
the AC power connection points labeled LINE,
NEUTRAL, and GROUND on the field-connection
terminal block. Connect to a circuit that is fed by the load
side of the transfer switch, so that it is backed up by the
generator. See Figure 3-3 and the wiring diagrams in
Section 6 for connection details.
