1.10 BATTERY INSTALLATION

NOTE:

Fill the battery with the proper electrolyte fluid if nec- essary 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 5 amp and 15 amp fuses from the generator control panel.

If the Auto/Off/Manual switch is not set to its OFF position, the generator can crank and start as soon as the battery cables are connected. If the utility power supply is not turned off, sparking can occur at the battery posts and cause an explosion.

Battery cables were factory connected at the genera- tor (Figure 1.5). 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 5 amp and 15 amp fuses in the gen- erator control panel.

NOTE:

Damage will result if battery connections are made in reverse.

Figure 1.5 – Battery Cable Connections

Your generator is equipped with a battery trickle charger that is active when your 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 your battery by maintaining the battery when the unit is not running. The trickle charge feature cannot be used to recharge a discharged battery.

1.11 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 350 cold-cranking amps minimum for 7 kW; 550 cold-cranking amps minimum for 12 and 15 kW at -18º 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 precautions are to be observed when working on batteries:

•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 dis- connecting 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.
