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 electric shock and
burns by high short-circuit current.
The likelihood of such shock can be reduced if such grounds are removed during installa-
tion and maintenance (applicable to equipment and remote battery supplies not having a
grounded supply circuit).
g) When replacing batteries, replace with the same type and number of batteries or battery packs.
CAUTION: Do not dispose of batteries in a fire. The batteries may explode.
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to the skin and
eyes. It may be toxic.
CAUTION: Risk of explosion if battery is replaced by an incorrect type. Dispose of used bat-
teries according to the instructions.
• The UPS has dangerous high voltages on its input and output connections. Contact with these
voltages may be life threatening.
• In case of emergency, immediately turn off the equipment and disconnect the power cord from
the AC power supply to disable the UPS.
• Do not allow any liquid or any foreign object to enter the UPS.
• The UPS is intended for indoor installation in a ventilated, controlled indoor environment with
a range of temperature between 0°C (+32°F) and +40°C (+104°F) and non-condensing humi-
dity <95%.
• Do not install the UPS in locations with sparks, smoke and hazardous gas or where there is water
and excessive humidity. Dusty, corrosive, and salty environments can damage the UPS.
• Do not plug the UPS input into its own output.
• Do not attach a power strip or surge suppressor to the UPS to avoid potential overloads.
• Ensure that the cables connecting the loads to the UPS are not longer than 10 meters.
• Keep a clearance of 20 cm beyond the UPS rear panel. Avoid exposing it to direct sunlight or
installing it near heat emitting appliances.
• Unplug the UPS prior to cleaning and do not use liquid or spray detergent.
• Do not place the UPS near equipments that generate strong electromagnetic fields and/or near
equipments that are sensible to electromagnetic fields.
• The battery of the UPS should be recharged every 2-3 months if unused. To do so, connect the
power cable to a suitable grounded mains socket.
• 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.
