Generator Set Connections
Note:
Read all safety precautions at the beginning of this publication before performing any work on the generator set.
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.
Before applying utility power to the generator or connecting the battery, connect the RXT transfer switch and any RBUS
accessories to the generator set terminal block (A, B, PWR, and COM).
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 12. Refer to the 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 the Ground and Neutral Connections section 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. Use separate conduit for the power leads and the low voltage leads.
4. For transfer switch communication and/or engine start connection, see the Automatic Transfer Switch Connection
section.
5. For connection of the optional programmable interface module (PIM), and/or a load shed kit, see the Accessory
Module RBUS Communication Connections section.
Connect utility power for the controller's battery charger and GFCI outlet. Connect the circuit to the load side of the
6.
transfer switch so that it is backed up by the generator. See the Power Supply section for more information about the
utility power requirement.
7. Install an AC receptacle for the optional AC accessories, if equipped. Power to this receptacle must be available when
the generator set is not running.
Note:
®
The OnCue Plus Generator Management System kit for remote generator monitoring and control is included with
Model RCL generator sets. The OnCue Plus system requires installation of a network cable from the generator to the
owner's computer router or the addition of the optional OnCue Plus Wireless kit.
8. To connect the OnCue
set to the customer's router or modem.
Note:
If the optional OnCue Plus Wireless kit is used, refer to the Installation Instructions provided with the kit.
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.
