4.6 ASSEMBLY PROCEDURE EXTERNAL BATTERY

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).
Batteries installation
For battery installation please respect the prescriptions of the EN62040-1 standard,
paragraph 7.6.
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 are installed (see
EN62040-1 annex M).
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 they can be subject to irreparable damage.
