Briggs & Stratton 040220A manual Battery Connection, Charging the Battery, Servicing the Battery

INSTALLATION

Battery Connection

The Home Standby Generator is supplied with a 12 Volt DC, AGM type, 33 Amp-Hour, valve regulated battery. It is a sealed, lead-acid rechargeable battery. It is installed in the unit and the battery cables are connected at the factory. The unit’s 15 Amp fuse, which isolates the battery and prevents the unit from starting, has been removed for shipping. The battery will lose some charge charge prior to installation of the generator. If battery voltage is below 12 Volts, charge the battery.

IMPORTANT: If battery voltage is below 5 Volts, it may not take a charge and you will need a new battery.

WARNING

Storage batteries give off explosive hydrogen gas during recharging.

Slightest spark will ignite hydrogen and cause explosion.

Battery electrolyte fluid contains acid and is

extremely caustic.

Contact with battery contents will cause severe chemical burns.

A battery presents a risk of electrical shock and high short circuit current.

•DO NOT dispose of battery in a fire.

•DO NOT allow any open flame, spark, heat, or lit cigarette during and for several minutes after charging a battery.

•DO NOT open or mutilate the battery.

•Wear protective goggles, rubber apron, and rubber gloves.

•Remove watches, rings, or other metal objects.

•Use tools with insulated handles.

Charging the Battery

If it is necessary to charge the battery, proceed as follows:

1.Set the generator's “AUTO/OFF/MANUAL” switch to OFF.

2.Remove the 15 Amp fuse from the control panel.

3.Disconnect the negative battery cable to the negative battery terminal (indicated by NEGATIVE, NEG, or (-).

NOTICE

Failure to disconnect negative battery cable will result in equipment failure.

•DO NOT attempt to jump start the battery.

•Damage to equipment resulting from failure to follow this instruction will void warranty.

WARNING

Battery posts, terminals and related accessories contain

lead and lead compounds - chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

NOTE: With the battery installed and utility power available to the Automatic Transfer Switch, the battery receives a trickle charge whenever the engine is not running. This process may take up to 72 hours to fully charge a battery. The trickle charge cannot be used to recharge a battery that is completely discharged.

5.Connect the negative battery cable to the negative battery terminal (indicated by NEGATIVE, NEG, or (-).

6.Ensure hardware on both positive and negative battery terminals is secure.

7.Reinstall the 15 Amp fuse in the control panel.

CAUTION

Installing the 15A fuse could cause the engine to start.

•DO NOT install this fuse until all plumbing and wiring has been completed and inspected.

8.Set the generator's “AUTO/OFF/MANUAL” switch to AUTO.

Servicing the Battery

If it is necessary to service the battery, proceed as follows:

1.Set the generator's “AUTO/OFF/MANUAL” switch to OFF.

2.Remove the 15 Amp fuse from the control panel.

3.Service or replace battery as required.

4.Connect the red battery cable to the battery positive terminal (indicated by POSITIVE, POS, or (+)).

5.Connect the negative battery cable to the negative battery terminal (indicated by NEGATIVE, NEG, or (-).

6.Ensure hardware on both positive and negative battery terminals is secure.

7.Reinstall the 15 Amp fuse in the control panel.

8.Set the generator's “AUTO/OFF/MANUAL” switch to AUTO.

4.Charge battery with battery charger at 2 Amps until battery holds 12 Volts.

NOTE: DO NOT exceed 13.7 Volts charging.
