1.10.2 TRANSFER SWITCH
1.10.2.1 15 kW Units
Transfer switches for use with this generator are sold
separately and can be purchased from dealers.
• Install any transfer switch in accordance with the
instructions supplied with the transfer switch.
• Failure to utilize a the manufacturer’s transfer
switch with this generator will void the warranty.
1.11 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. Set the generator's AUTO/OFF/MANUAL switch to
OFF.
2. Turn off utility power supply to the transfer
switch.
3. Remove the 7.5 amp and 15 amp fuses from the
generator control panel.
Battery cables were factory connected at the genera-
tor (Figure 1.3). Connect cables to battery posts as
follows:
4. Connect the red battery cable (from starter con-
tactor) 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 nega-
tive, NEG or (—).
6. Replace the 7.5 amp and 15 amp fuses in the
generator control panel.
NOTE:
Damage will result if battery connections are made
in reverse.

‹ NOTE:
The generator is equipped with a battery trickle
charger that is active when the unit is set up for
automatic operation. With the battery installed
and utility power source voltage available to the
transfer switch, the battery receives a trickle
charge while the engine is not running, to prevent
self-discharge. The trickle charger is designed to
help extend the life of the battery by maintain-
ing the battery when the unit is not running. The
trickle charge feature cannot be used to recharge
a discharged battery.
1.12 THE BATTERY
Servicing of the battery is to be performed or super-
vised by personnel knowledgeable of batteries and
the required precautions. Keep unauthorized person-
nel away from batteries.
When replacing the battery, use the following type of
battery: Group 26/26R 12-volt battery with a rating
of 525 cold-cranking amps minimum for 15 kW at
-17.8º C (0º F) minimum. When using a maintenance-
free battery, it is not necessary to check the specific
gravity or electrolyte level. Have these procedures
performed at the intervals specified in the “Service
Schedule.” A negative ground system is used. Battery
connections are shown on the wiring diagrams. Make
sure the battery is correctly connected and terminals
are tight. Observe battery polarity when connecting
the battery to the generator set.
DANGER

Do not dispose of the battery in a fire. The
battery is capable of exploding.

A battery presents a risk of electrical shock
and high short circuit current. The following pre-
cautions are to be observed when working on
batteries:
• Remove the 7.5A and 15A fuses from the genera-
tor control panel;
• Remove watches, rings or other metal objects;
• Use tools with insulated handles;
• Wear rubber gloves and boots;
• Do not lay tools or metal parts on top of the
battery; and
• Disconnect charging source prior to connecting or
disconnecting battery terminals.

Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.

The electrolyte is a dilute sulfuric acid that is
harmful to the skin and eyes. It is electrically
conductive and corrosive.
