Route AC leads through flexible conduit. Ensure that
the leads and conduit do not interfere with the operation
of the generator set or obstruct the service areas. Route
low-voltage communication leads through separate
conduit.
Procedure
1. Drill holes for the conduit fittings. See Figure 1-16
and Appendix B for the recommended electrical
inlet locations.
Feed the cables through the
openings.
2. Connect the leads from the transfer switch
emergency source lugs to the L1 and L2
connections on the generator set terminal block.
3. Connect the neutral (L0) and ground (GRD) leads
from the ATS and the main panel to the
corresponding connection points on the terminal
block. See Section 1.8.1, Grounding.
4. Connect utility power leads to the terminal block
connections labelled Utility. Connect to a circuit
that is supplied by the utility source and backed up
by the generator. The power source must be GFCI
protected. See Section 1.8.4 for more information
about the utility power requirement.
5. For connection of optional transfer switches, the
programmable interface module (PIM), and/or a
load control module (LCM), see Section 1.8.5.
6. If the OnCue Home 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.
Note: Installation of the network cable at the time
of generator set installation is highly
recommended. Installing the Ethernet cable
now will make connection much easier if you
choose to add OnCue later.
a. Route the network cable with other low-voltage
signal
wiring
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 1-17. The inline
coupler is included with the OnCue kit.

Power Supply
120 VAC, 60 Hz power must be supplied to the
generator set location for the battery charger (integral to
the RDC2 and DC2 controllers) and the optional
accessories shown in Figure 1-18. The power source
must be GFCI protected. The power to the accessories
must be available at all times, i.e. the circuit must be
powered by the utility source and backed up by the
generator.
Be sure to disconnect power at the distribution panel
before making the connections. Connect power leads to
the utility power connection points on the terminal block.
See Section 1.8.3 and the wiring diagrams in Section 2
for connection details.
