WARNING
In the event of a malfunction, the battery cabinet chassis or battery
cabinet frames may become live!
Take special care when working with the battery cabinet associated
with the equipment. Make sure that 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 that you make sure that the
batteries are installed separately, in a dedicated battery cabinet.
Do not exceed the battery back-up time of one hour.
CAUTION
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 off is less than for flooded cells, but when planning the
battery installation, allowance must be made for adequate ventilation
and heat dissipation.
Valve-regulated cells are not completely maintenance-free. They must
be kept clean and their connections checked periodically to ensure that
they are tight, and that there is no evidence of corrosion. The batteries
lose charge during transportation and storage, so before you attempt
to carry out an autonomy test, make sure 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 satisfied when battery
cabinets are used with original accessories. If alternative batteries are
used, make sure that the applicable EC directives are met and declare
conformity.
Connect the battery cabinet as follows:
1.
Turn off the UPS.
2.
Check that all the external battery breakers are open.
3.
Connect PE first.
