• The UPS is equipped with an auto-restart system. In case of return of the input mains after the end of
battery operation, the UPS turns on to normal operation by supplying the output loads.
• The UPS is equipped with an automatic backfeed protection system.
• When installing the equipment, ensure that the sum of the leakage current of the UPS and the
connected equipment does not exceed 3.5 mA.
CAUTION
The batteries inside the UPS are not user replaceable. Servicing of batteries must be performed only by
electrical hazard authorized personnel.
A battery can present a risk of electrical shock and burns by high short-circuit circuit current. Failed
batteries can reach temperatures that exceed the burn thresholds for touchable surfaces. 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 to 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).
g) never leave live cable terminals without an insulated protection.
h) When replacing batteries, replace with the same type and number of batteries or battery packs. There
is the risk of explosion if batteries are replaced by an incorrect type.
CAUTION
Do not dispose of batteries in a fire. The batteries may explode.
Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.
For the disposal requirements refer to local laws and relevant standards.
