INFORMATION

1.10 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 7.5A and 15A fuses from the

generator control panel.

Battery cables were factory connected at the generator (Figure 1.5). Connect cables to battery posts as follows:

4.Connect the red battery cable (from starter contactor) 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 negative, NEG or

(--).

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 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

_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 the 7.5A and 15A fuses from the generator 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.

°_ WARNING _=

_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.

The following procedures are to be observed:

•Wear full eye protection and protective clothing;

•Where electrolyte contacts the skin, wash it off immediately with water;

•Where electrolyte contacts the eyes, flush thoroughly and immediately with water and seek medical attention; and

•Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to use a solution of 1 pound (500 grams) bicarbonate

of soda to 1 gallon (4 liters) of water. The bicarbonate of soda solution is to be added until

the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the area dried.

_ Lead-acidbatteries present a risk of fire because they generate hydrogen gas. The

following procedures are to be followed:

•DO NOT SMOKE when near the battery;

•DO NOT cause flame or spark in battery area; and

•Discharge static electricity from body before touching the battery by first touching a grounded metal surface.

_Be		sure the	AUTO/OFF/MANUAL		switch is set to
	the OFF position before connecting the battery
	cables. If the switch is set to AUTO or MANUAL,
	the generator can crank and start as soon as
	the	battery	cables	are connected.
_Be		sure the	utility	power supply	is turned off
	and the 7.5A and 15A fuses are removed from

the generator control panel, or sparking may occur at the battery posts as the cables are attached and cause an explosion.
