8.4 Positioning and Connection of the Batteries
Risk of electric shock
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).
Follow the installation instructions
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, the rule stated by NFC 15-100 article 554.2 must be
applied: the volume of the renewed air has to be at least 0,05 NI m3 per hour, where N is the
number of the elements inside the battery and I is maximum current of the rectifier.
The batteries can either be internal or external; 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.
Auxiliary contact of the external battery switch
For a correct operation of the UPS it is advisable to connect the auxiliary contact of the external
battery switch to the terminals X10-9/10.
