Main AC Wiring
NOTE: Main AC wiring must be in accordance with local
jurisdiction and codes.
Strip the insulation off the wire ends. Do not
1.
remove excessive insulation.
Remove the two cap plugs located behind the
2.
breaker door and to the right of the Main Breaker.
Loosen the lugs of the Main Breaker through the
3.
access holes.
Insert a power wire (E1 or E2) through the opening
4.
in the back cover and into the bottom lug. Torque to
the proper specification.
NOTE: There are 3 screws inside the top of the breaker
panel (behind the breaker door). Removing these screws
will allow the entire breaker box to be carefully pulled out.
When reinstalling, be certain that the tabs on the bottom
lock into place.
Connect the Neutral wire to the Neutral Lug if
5.
applicable. Torque to the required specification.
See
Table 6-2.
Connect the Ground wire to the Ground Lug and
6.
torque to the required specification. See
NOTE: Neutral Bonding - For installations that require
the neutral to be bonded to the ground, this is to be done
on the customer connections terminals inside the
generator. Connect a suitably sized wire from the neutral
bar to the ground bar. This is normally required when the
generator is the source in a separately derived system. It
is not required when the generator is a backup source in
a utility supplied electrical system with a 2-pole transfer
switch. See
Figure
6-1.
NOTE: Torque all wiring lugs, bus bars and connection
points to the proper torque specifications. Torque
specifications for the Main Line Circuit Breaker (MLCB)
can be found on a decal located on the inside of the Main
Line Circuit Breaker Door.

Battery Installation
WARNING
24
Fill the battery with the proper electrolyte fluid if
necessary and have the battery fully charged before

avoid spark. Failure to do so could result in
death or serious injury.
Connect the red battery cable (from starter
4.
contactor) to the battery post indicated by a
positive, POS or (+).
Connect the black battery cable (from frame
5.
ground) to the battery post indicated by a negative,
NEG or (-).
Install the red battery post cover (included).

NOTE: Dielectric grease should be used on battery
posts to aid in the prevention of corrosion.
NOTE: Damage will result if battery connections are
made in reverse.
