6.1 — General Information
All wiring must be properly sized, routed, supported, and connected. All wiring must comply with NEC and local codes.
The generator uses Customer Connection Interface (CCI) panels to separate the high voltage and customer control
wiring connections. These two panels are clearly labeled. The wiring diagrams for each specific unit show the
connection points in their corresponding sections. Terminal boards are clearly labeled and correspond to the same
terminal connections shown in the wiring diagrams. Always use the unit specific wiring diagrams when making wiring
connections.
6.2 — Remove Rear Panel and Stub Up Cover
See Figure 6-1. Remove six screws with nylon washers to release rear panel from enclosure. For best results,
1.
rotate left side of panel outward away from enclosure before disengaging the right side.
Remove four screws with nylon washers to release fascia from control panel.
2.
The stub up cover and five screws with flat washers are shipped loose and found inside the enclosure.

6.3 — Wiring Installation Safety
Review the safety rules at the beginning of this manual for specific dangers, cautions, and hazards associated with the
installation of industrial products.
When installing the generator set and connecting wiring, keep the generator and system de-energized and disabled. It
is common electrical safety practice to verify that wires are de-energized using appropriate safety gear and a meter
before handling. Disable the generator by placing the AUTO/OFF/MANUAL switch in the OFF position, de-energize the
battery charger, and disconnect the negative cable from the negative battery terminal. Also, make sure the auxiliary
power circuit to the unit is de-energized.
6.4 — General Wiring Requirements
Consider the following general wiring requirements:
Load Wiring - Properly size and select wiring.
•
Control Wiring - Typically low DC voltage wiring (12 Vdc)
•
that includes the 2-wire start and signal wiring. Use multi-
strand wire appropriately sized for the length of run. Do
not exceed #12 AWG when connecting to the customer
connection terminals.
Accessory Power Wiring - Provides power for optional
•
user accessories (battery warmer and block heater). Size
and select wiring using the appropriate tables in the NEC
and per the connection requirements in the individual
control panel wiring diagram.
6.5 — High Voltage Connections
The customer connection area on the left side of the control
panel contains the terminals to connect all high voltage wiring.
These connections are as follows:
MLCB - E1, E2, E3 (if three-phase), and Neutral for cus-
•
tomer load wiring. These wires run from the main line cir-
cuit breaker to the transfer switch. They supply generator
power to the transfer switch and are marked for easy
identification.
