Section 1 — General Information

15 kW Generator

‹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.
