2 Safety and Operating Instructions
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 humidity
<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.
• 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.
WARNING
The UPS is a category C2 product according to the EN 62040-2. In a residential environ-
ment, the equipment may cause radio interference, in which case the user may be required to
take additional measures.
