TP-6906 6/14 21Section 1 Installation Instructions
Generator Set Connections
Use separate conduit for the power cables and the low
voltage communication or engine start leads. Local
codes and the length of run as well as the transfer switch
wire size requirements will determine the wire size
needed for the AC leads.
Note: Some codes require the use of a disconnect
switch. Check the code requirements for your
location and install a disconnect switch, if
required.
1. Route the load leads into the junction box through
the access opening in the bottom of the box.
Connect the load leads from the line circuit breaker
in the generator set junction box to the transfer
switch emergency power connection points. See
Figure 1-10 and refer to transfer switch installation
manual for ATS connection instructions.
2. Connect the neutral (L0) and ground (GRD) leads
from the ATS and the main panel to the
corresponding lugs in the connection box. See
Section 1.4.3 for grounding information.
3. Cut or punch openings in the side of the connection
box for the 120 VAC power supply leads and the
low voltage connections. See Figure 1-10. Use
separate conduit for the power leads and the low
voltage leads.
4. Connect utility power for the controller’s battery
charger. Connect to a circuit that is supplied by the
utility source and backed up by the generator. See
Section 1.4.5 and Figure 1-10 for more information
about the utility power requirement.
5. For transfer switch communication and/or engine
start connection, see Section 1.4.7.
6. For connection of the optional programmable
interface module (PIM), and/or load control module
(LCM), see Section 1.4.9.
7. Install an AC receptacle for the optional oil pan
heater and/or battery heater, if equipped. Power to
this receptacle must be available when the
generator set is not running.
Note: Optional OnCuer Plus and OnCuer Plus
Wireless Generator Management System kits
are available for remote generator monitoring
and control. The OnCue Plus system requires
installation of a network cable from the generator
to the owner’s computer router. OnCue Plus
Wireless does not require installation of a
network cable to the owner’s router.
8. 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.
Note: Installation of the network cable at the time
of generator set installation is highly
recommended (unless installing OnCue
Plus Wireless). Installing the Ethernet cable
now will make connection much easier if you
choose to add OnCue Plus later.
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. The inline coupler is included
with the OnCue Plus kit.
