WARNING
Automatic startup of the generator set during installation can cause severe personal injury
or death.
Make sure the generator set is shut down and disabled:
a. Press the generator set's red STOP button on the local display 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.
CAUTION
Ensure that AC power to the generator set has been de-energized and locked out to prevent
accidental energizing of the circuit.
NOTICE
The oil and battery heaters run on AC power supplied by the utility. The regulator heater
runs on DC power supplied by the generator set battery. The energy supplied by the battery
for the regulator heater comes from the same source as the generator set-mounted battery
charger. If the battery charger is not operating, the generator set battery will eventually
discharge enough to not start the generator set.
NOTICE
Prior to the start of the oil heater installation, the correct engine oil must be available, and
must conform to the requirement listed in the operator manual. This may be a different oil
than what is currently in the engine.
a. Prior to installing the oil heater, the engine oil must be drained. Follow the oil drain procedure
in the generator set operator manual.
b. Remove the panels shown below.
