1.9.1

Grounding

Ground the generator set. The grounding method must

comply with NEC and local codes. Connect the ground

to the generator set ground lug, terminal GND inside the

controller compartment.

The requirement for having a bonded (grounded)

neutral or ungrounded neutral is determined by the type

of installation. At installation, the neutral can be

grounded at the generator set or lifted from the ground

stud and isolated if the installation requires an

ungrounded neutral connection at the generator. The

generator set will operate properly with the neutral either

bonded to ground or isolated from ground at the

generator.

Note: When shipped, the generator neutral is not

bonded (grounded) to the generator ground.

Various regulations and site configurations including the

National Electrical Code (NEC), local codes, and the

type of transfer switch used in the application determine

the grounding of the neutral at the generator. NEC

Section 250 is one example that has a very good

explanation of the neutral grounding requirements for

generators.

Field-Connection Terminal Block

The generator set is equipped with a field-connection

terminal block located in the air inlet area inside the

junction box. Leads have been factory-installed from the

junction box to the terminal block for easy field wiring.

See Figure 1-17 for terminal block location. Remove the

cover panel for access to the field connections.

Location

See Figure 1-18 for terminal block details. Refer to the

terminal block decal for connections and cable sizes.

Also see the wiring diagram in Section 3.

Route AC leads through flexible conduit. Ensure that the

leads and conduit do not interfere with the operation of

the generator set or obstruct the service areas. Route

low-voltage communication leads through separate

conduit.
