3.10.4 Charge Battery
Use a battery charger to maintain a fully charged battery when the generator set is used in a standby application. The engine
battery-charging alternator charges the battery while the generator set is running. Refer to the battery charger operation manual
for installation, operation, and service procedures.
Note:
If the generator set is in a temporary prime power application in which the generator set has periods of inactivity, the controller
circuitry may drain the battery. If there is no power source for a battery charger, place the controller in the prime power mode, if
equipped, or disconnect the battery from the generator set.
3.11 Storage Procedure
Perform the following storage procedure before taking a generator set out of service for three months or longer. Follow the
engine manufacturer’s recommendations, if available, for fuel system and internal engine component storage.
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before working on the generator set. Remove the
negative (–) lead first when disconnecting the battery. Reconnect the negative (–)
lead last when reconnecting the battery.
Disabling the generator set. Accidental starting can cause severe injury or death. Before working on the generator set or
equipment connected to the set, disable the generator set as follows: (1) Move the generator set master switch to the OFF
position. (2) Disconnect the power to the battery charger. (3) Remove the battery cables, negative (–) lead first. Reconnect the
negative (–) lead last when reconnecting the battery. Follow these precautions to prevent starting of the generator set by an
automatic transfer switch, remote start/stop switch, or engine start command from a remote computer.
Hot engine and exhaust system.
