4200FA XT 80kVA Installation and Operation Manual
CAUTION
This unit contains sealed lead acid batteries. Lack of preventative
maintenance could result in batteries exploding and emitting gasses
and/or flame. An authorized technician must perform annual preventative maintenance.
CAUTION
Failure to replace a battery before it becomes exhausted may cause
the case to crack; possibly releasing electrolyte from the battery
resulting in secondary faults such as odor, smoke, and fire.
CAUTION
Only personnel knowledgeable of batteries and the required
precautions should perform installation and servicing of batteries. Keep
unauthorized personnel away from the batteries.
CAUTION
Proper maintenance to the battery system of this unit must be done by
a qualified service technician. This is essential to the safety and
reliability of your UPS system. Refer to service manual.
DANGER
A battery can present a risk of electrical shock and high short
circuit current.
The following precautions should be observed
when working with batteries:
TO BE PERFORMED BY QUALIFIED PERSONNEL ONLY!
1)
Verify that the UPS is off and is disconnected from the power source.
2)
Remove watches, rings, jewelry, or other metal objects.
3)
Use tools with insulated handles to prevent inadvertent shorts.
4)
Wear rubber gloves and boots.
5)
Do not place tools or metal parts on top of the batteries.
6)
Determine if the battery is inadvertently grounded. If inadvertently grounded, remove
source of ground.
Contact with any part of a grounded battery can result in
electrical shock.
The likelihood of such shock will be reduced if such grounds are
removed during installation and maintenance.
7)
Verify circuit polarities prior to making connections.
8)
Disconnect charging source and load prior to connecting or disconnecting terminals.
9)
VRLA batteries contain an explosive mixture of hydrogen gas. Do not smoke, or create a flame
or spark in the immediate area of the batteries. This includes static electricity from the body.
10)
Do not attempt to open the batteries in order to add water or sample the specific gravity of the
electrolyte. The batteries are valve-regulated lead acid type and such servicing is not possible
without damaging the battery.
11)
Use proper lifting means when moving batteries and wear all appropriate safety clothing and
equipment.
12)
Do not dispose of lead acid batteries except through channels in accordance with local, state
and federal regulations.
