2.5 Power Supply
Power must be supplied to the generator set location for the battery charger and optional accessories. The power source must
comply with both state and local codes. 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 set.
Connect power to the leads in the utility power connection area as shown in the Generator set Connections figure. Connect
the circuit to the load side of the transfer switch so that it is backed up by the generator. See the wiring diagrams in the Diagrams
and Drawings section for connection details. See Figure 11 for the power requirements for the battery charger and accessories.

2.6 Connect AC and DC Wiring
Note:
Have a licensed electrician make the following electrical connections. All connections must comply with state and local codes.
Size the wire according to the length of run and 115% of the circuit current (amperage) based on 75°C wire rating or less as
directed by the National Electrical Code
®
(NEC) in ANSI/NFPA 70. See the Electrical Connections section for additional
information about wire selection.
The generator set is equipped with a field-connection terminal block located in the access area below the junction box. Leads
have been factory-installed from the junction box to the terminal block for easy field wiring.
Make all AC and DC customer connections inside the customer connection box. Do not remove the end panel or make
connections inside the junction box. Refer to the wiring diagrams in the Diagrams and Drawings section.
