NOTICE
When using a circuit breaker with an adjustable, electronic trip unit, the
amperage and trip curve settings may need adjustment to match the
generator set load wiring, or downstream loads and circuit breakers. An
accessory seal kit (part number A026M166) is available to tamper-proof the
adjustable settings.
1. Make sure the generator set is shut down and disabled:
a. Press the Off switch from the display and then press the E-Stop button to
stop the generator set. Allow the generator set to thoroughly cool to the
touch.
b. Turn off and disconnect the battery charger from the AC source before
disconnecting the battery cables.
c. Disconnect the negative (–) cable from the battery and secure it from
contacting the battery terminals to prevent accidental starting.
2. Remove the enclosure side panel to gain access to the main circuit box.
3. Place the circuit breaker handle in the OFF position.
4. Remove the four bolts holding the circuit breaker cover.
5. Connect the conductors to the circuit breaker load-side terminals, neutral lug,
and equipment grounding lug. For grounding and neutral connections, look for
the symbols on the generator set circuit breaker box (shown below, and in the
next image at the bottom).
