OBET, OBETXU, ON BOARD Battery Chargers

INTRODUCTION:

SOME APPLICATIONS:

Golf cars, pallet trucks, personnel carriers, scissor lifts, floor scrubbers, robotics.

IMPORTANT: DO NOT USE THIS CHARGER UNTIL YOU HAVE READ ALL THE
INSTRUCTIONS.

INITIAL INSTALLATION:

Before making AC connections, refer to the AC requirements labeled on the charger. If your
charger is not equipped with an AC plug (a 220 volt model) have a qualified electrician install
one.

CAUTION: To reduce the risk of fire, use this charger only on circuits provided with
a maximum of 20 ampere branch circuit protection (circuit breaker or fuse),

In accordance with the National Electric Code, ANSI/NFPA 70, and all local
codes and ordinances.

GROUNDING INSTRUCTIONS:
This battery charger must be grounded to reduce the risk of electric shock. If the charger is
equipped with a grounding type plug, it must be plugged into a nominal 115 volt, 60 Hertz
circuit. If the charger is supplied with no plug, have a qualified service person install one.

WARNING: Improper connection of the equipment grounding conductor can result in a
risk of an electric shock. DO NOT USE THIS CHARGER ON A TWO

POLE UNGROUNDED OUTLET OR ATTEMPT TO BREAK OFF
THE GROUND PRONG FOR USE ON A RECEPTACLE OR
EXTENSION CORD NOT HAVING A GROUND.

The use of an extension cord with this charger should be avoided. The use of an improper
extension cord result in a risk of a fire or electric shock. If an extension cord must be used, make
sure it is in good condition. Use a three conductor cord no smaller than 16 AWG. And keep it as
short as possible. Locate all cords so that they will not be stepped on, tripped over, or otherwise
subjected to damage or stress.

Do not operate this charger if it shows any signs of physical damage.

PROPER CARE AND USE OF BATTERIES:

CAUTION: Always wear protective eye shields and clothing when working with batteries.

Batteries contain acids which can cause bodily harm. Do not put wrenches or

Other metal objects across the battery terminal or battery top. Arcing or

explosion of the battery can result. Do not wear jewelry when working around

batteries. Arcing can cause sever burns.

New batteries will not deliver their full performance until after several cycles.

The tops of the batteries and battery hold downs must be kept clean and dry at all times to
prevent excessive self discharge and flow of current between the battery post and frame.

Maintain the proper electrolyte level by adding water when necessary. Never allow the
electrolyte level to fall below the top of the battery plates. Electrolyte levels fall during
discharge and rise during charging. Therefore, to prevent the overflow of electrolyte when
charging, add water ONLY AFTER the batteries have been fully charged DO NOT
OVERFILL. Old batteries require more frequent additions of water than do new batteries.

Do not over discharge the batteries. Excessive discharge can cause polarity reversal of
individual cells resulting in complete battery failure.

Provide adequate ventilation for the batteries and charger. Do not obstruct the flow of cooling air
around the charger. Provide at least 1" of space around charger. Do not allow clothing, blankets
or other material to cover the charger. Mount the charger firmly in place.

WARNING: Chargers can ignite flammable materials and vapors. Do not use near fuels,

grain, dust, solvents, or other flammable’s.

CAUTION: Before connecting the charger to the batteries, make sure the battery pack is of
the same voltage rating of the charger. If you are unsure, count the number of

cells on the battery pack and multiply by two. This figure should be the same

as the DC voltage rating of the charger. (see ratings label on charger).

Below is an illustration of Parallel and Series battery packs.
