when operating the battery. Otherwise, you may become blind if acid enters your eyes and your skin
may be damaged by the acid.
At the end of battery life, the battery may have internal short circuit, drain of electrolytic and erosion
of positive/negative plates. If this condition continues, the battery may have temperature out of
control, swell or leak. Be sure to replace the battery before these phenomena happen.
If a battery leaks electrolyte, or is otherwise physically damaged, it must be replaced, stored in a
container resistant to sulfuric acid and disposed of in accordance with local regulations.
If electrolyte comes into contact with the skin, the affected area should be washed immediately with
water.
2.2 Battery cabinet typologies
According to the requested UPS configuration may need internal and/or external batteries Modular UPS can
utilize two different battery typologies:
Modular: consisting of a number of battery boxes each containing 10 batteries that cannot be accessed
w/o removing a protective cover, installed in the UPS and / or in a dedicated Modular Battery Cabinet
(MBC) that allows to extend the runtime as long as the systems or it’s requirements grown adding
additional battery modules on-the-fly by means of touch free blind mate connectors.
Traditional: consisting of one or more strings of battery blocks installed on shelves in a locked cabinet
or dedicated battery room
Note
The battery modules, regardless if they are mounted internally to the UPS or in the MBC, make uses of
strings of 40 batteries.
The Traditional external battery cabinet can make use of each even number of battery per string between
36 and 44.
The default factory setting, if the unit is ordered w/o internal battery is 40 batteries.
The cabinet is only for valve regulated maintenance-free lead-acid battery.
CAUTION: The lead acid battery may cause chemistry hazard
