TP-6906 4/16 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 a load shed kit, see
Section 1.4.9.
7. Install an AC receptacle for the AC accessories, if
equipped. Power to this receptacle must be
available w hen the generator set is not running.
See Figure 1-9 for accessory power requirements.
8. To connect the OnCuer Plus Generator
Management System to your generator, run
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. Test the Internet connection for the generator
by connecting a laptop to the network cable.
(1) Turn OFF any wireless connections to the
laptop.
(2) Connect the network cable to the laptop.
Connect the other end of the network cable
to the customer’s router or modem.
(3) Verify the Internet connection by opening
your web browser and going to
www.kohlerpower.com or any known
website.
(4) Disconnect the network cable from the
laptop.
c. 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.
