4.8. Battery System Installation

External Battery Cabinet Installation (EBC)

Before connecting the external battery, please read the notice and warning label on the battery cabinet.

WARNING

• In the event of malfunction, the battery cabinet chassis or battery cabinet frames may become

live!.

• Special care should be taken when working with the battery cabinet associated with the

equipment. Ensure the battery number is suited to the setting of the battery charging voltage

before installing the battery. When the battery cabinet is connected the overall voltage exceeds

nominal voltage. It is very important to ensure that the batteries are installed separately, in a

dedicated battery cabinet.

• Battery back-up time do not exceed one hour, if the battery setting shall be exceeded one

hour, consult to the professional personnel.

NOTE

• The most common battery type used in UPS installations is the valve regulated battery. Valve

regulated cells are not sealed. The amount of gas given o󰀨 is less than for ooded cells, but

when planning the battery installation, allowance must be made for adequate ventilation and

heat dissipation. Valve regulated cells are not completely maintenacefree. They must be kept

clean and their connections checked periodically to ensure they are tight, and that there is no

evidence of corrosion. It is inevitable that the batteries will lose charge during transportation

and storage; before attempting to carry out an autonomy test, ensure that the batteries are

fully charged as this may take several hours. Cell performance typically improves after a few

discharge/recharge cycles.

• The requirements of the EC directives are satised when battery cabinet are used with

original accessories. If alternative batteries are used, you must ensure that the applicable EC

directives are met and declare conformity.

The default battery settings of the UPS are for 12 Vdc VRLA batteries. If requested to use other

battery types, contact your Eaton representative. For the battery specication, see Section

8.4 Battery
