2. Remove the two cap plugs located behind the breaker door and to the right of the Main Breaker.
3. Loosen the lugs of the Main Breaker through the access holes.
4. Insert a power wire (E1 or E2) through the opening in the back cover and into the bottom lug. Torque to the
proper specification.
NOTE: There are three (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.
5. Connect the Neutral wire to the Neutral Lug and torque to the required specification. See Figure 6-1.
6. Connect the Ground wire to the Ground Lug and torque to the required specification. See Figure 6-1.
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 neu-
tral 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.

Group 26R, 12V, 525 CCA (Minimum CCA)
6.5 — Battery Installation
Fill the battery with the proper electrolyte fluid if necessary and have the battery fully charged before installing it.
Before installing and connecting the battery, complete the following steps:
1. Verify that the generator has been turned OFF.
2. Turn off utility power supply to the transfer switch.
3. Remove the 7.5A fuse from the generator control panel.
Battery cables were factory connected at the generator. See Figure 6-3. Connect cables to battery posts as follows:
4. Connect the red battery cable (from starter contactor) to the battery post indicated by a positive, POS or (+).
5. Connect the black battery cable (from frame ground) to the battery post indicated by a negative, NEG or (—).
6. 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.
