Important Safety Warnings
This manual contains instructions and warnings that should be followed during the
installation, operating and storage of the UPS system. Please keep this manual for
further reference.
CAUTION! To prevent the risk of fire or electric shock, install in a temperature and humidity
controlled indoor area free of conductive contaminants. (See the specifications for the
acceptable temperature and humidity range.)
CAUTION! To reduce the risk of overheating the UPS, do not cover the UPS' cooling vents and
avoid exposing the unit to direct sunlight or installing the unit near heat emitting appliances
such as space heaters or furnaces.
CAUTION! Do not attach non-computer-related items, such as medical equipment,
life-support equipment, microwave ovens, or vacuum cleaners to UPS.
CAUTION! Do not plug the UPS input into its own output.
CAUTION! Do not allow liquids or any foreign object to enter the UPS. Do not place beverages
or any other liquid-containing vessels on or near the unit.
CAUTION! In the event of an emergency, press the OFF button and disconnect the power
cord from the AC power supply to properly disable the UPS.
CAUTION! Do not attach a power strip or surge suppressor to the UPS.
CAUTION! If the UPS is with metal chassis, for safety purpose, grounding is a must during
UPS installation in order to reduce leakage current below 3.5mA.
Attention hazardous through electric shock. Also with disconnection of this unit from the
mains, hazardous voltage still may be accessible through supply from battery. The battery
supply should be therefore disconnected in the plus and minus pole at the quick connectors of
the battery when maintenance or service work inside the UPS is necessary.
CAUTION! Servicing of batteries should be performed or supervised by personnel
knowledgeable of batteries and the required safety precautions. Keep unauthorized
personnel away from batteries.
CAUTION! When replacing the batteries, use the same number and type of batteries.
CAUTION! Internal battery voltage is 12VDC. Sealed, lead-acid, 6-cell battery.
CAUTION! Do not dispose of batteries in a fire. The battery may explode. Do not open or
mutilate the battery or batteries. Released electrolyte is harmful to the skin and eyes.
CAUTION! Unplug the UPS prior to cleaning and do not use liquid or spray detergent.
CAUTION! A battery can present a risk of electric shock and high short circuit current. The
following precaution should be observed before replacing batteries:
1) Remove watches, rings, or other metal objects.
2) Use tools with insulated handles.
3) Wear rubber gloves and boots.
4) Do not lay tools or metal parts on top of batteries.
5) Disconnect charging source prior to connecting or disconnecting batteries terminal.
Typical 4-8 ms, 13 ms max.
4-6 hours recover to 90% capacity
