Gamatronic Centric Series Installation Manual page 8


Battery installation, battery maintenance, and battery replacement shall be performed only by
authorized service personnel.

Pay attention to all DANGER, CAUTION, and WARNING notices affixed to the inside and outside
of the UPS.

Keep the surroundings clean, uncluttered and free from excess moisture.

Keep the operating environment within the parameters stated in this document.

Allow only qualified technicians to service the UPS. There are no user-serviceable components. Do
not try to repair it yourself!

Use the UPS only for its intended purpose.

The batteries should preferably be installed next to the UPS, or as close to it as is practically
possible.

If you remove a UPS module from the Centric while the module is operating, wait five minutes
before reinserting the module. This allows the module's capacitors time to discharge.

FAST FUSES (SEMICONDUCTOR FUSES) must be used between the battery and the Centric,
and on the rectifier ac input line. For example, the Ferraz Shawmut A70QS fuse.
WARNING - RISK OF LETHAL ELECTRIC SHOCK:
The battery cabinet contains a series of batteries that provides high voltage and energy in
the UPS body even when the UPS is not connected to the ac input.
Take appropriate precautions during installation, inspection and servicing.
WARNING - RISK OF LETHAL ELECTRIC SHOCK:
Units that come with internal manual/maintenance bypass circuit breakers are under high
voltage. All internal parts of the UPS remain under high voltage until ALL ac and dc has
been turned off from their CBs or fuses.
