POSITIONING AND CONNECTION OF BATTERIES
CAUTION
A battery can present a risk for electrical shock and high short circuit current. The
following precautions should be observed when working on batteries:
a)
Remove watches, rings or other metal objects;
b)
Use tools with insulated handles;
c)
Wear rubber gloves and boots;
d)
Do not lay tools or metal parts on top of batteries;
e) Disconnect the charging source prior connecting or disconnecting battery
terminals;
f)
Determine if battery is inadvertently grounded. If inadvertently grounded,
remove source from ground. Contact with any part of a grounded battery can
result in electrical shock. The likelihood of such shock can be reduced if such
grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).
IMPORTANT
For battery installation please respect EN62040-1-2 strictly and follow the installation
manual of the UPS.
To obtain the battery life indicated by the battery manufacturer, the operating
temperature must remain between 0 and 25 °C. However, although the battery can
operate up to 40°C, there will be a significant reduction of the battery life.
To avoid the formation of any kind of potentially explosive hydrogen and oxygen
mixture, suitable ventilation must be provided where the battery is installed (see
EN62040-1-2 annex N).
For the materials installed in France, we have to apply the rules according to NFC
15-100 article 554.2: the volume of the renewed air has to be at least 0,05 NI m
3
per
hour, where N is the number of the elements inside the battery and I is maximum
current of the rectifier.
The batteries can be internal or external; however it is recommended to install them
when the UPS is capable of charging them. Please remember that, if the battery is not
charged for periods over 2-3 months it can be subject to irreparable damage.
IMPORTANT
UPS B8031FXS and B8033FXS from 10 to 20kVA have internal batteries.
Servicing of batteries should be performed by qualified personnel only.
Replace the batteries with the same number of cells and capacity.
Replace only with original batteries.
CAUTION:
do not expose the battery to heat sources. It may explode.
CAUTION:
do not open the battery container. Released electrolyte is harmful to
the skin and eyes. It may be toxic.
CAUTION:
do not dump the exhausted batteries in the environment.
For the battery installation follow the instructions in the Operating Manual.
