Important Safety Instructions
To safely operate this uninterruptible power supply system, please read and follow all instructions
carefully. Please read this manual thoroughly before attempting to unpack, install, or operate UPS,
and keep this manual for further reference.
This UPS utilizes voltages that may be hazardous. Do not attempt to disassemble the unit.
The unit contains no user replaceable parts. Only authorized service personnel may
perform repairs.
Internal battery voltage is 12V DC. Sealed, lead-acid, 6 cells battery.
Connection to any other type of receptacle other than a two-pole, three-wire grounded
receptacle may result in shock hazard as well as violate local electrical codes.
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.
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.
This unit intended for installation in a controlled environment (temperature controlled,
indoor area free of conductive contaminants). Avoid installing the UPS in location where
there is standing or running water, or excessive humidity.
DO NOT plug the UPS input into its own output.
DO NOT attach a power strip or surge suppressor to the UPS.
DO NOT attach non-computer-related items, such as medical equipment, life-support
equipment, microwave ovens, or vacuum cleaners to UPS
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.
Unplug the UPS prior to cleaning and do not use liquid or spray detergent.
DO NOT dispose of batteries in a fire as they may explode.
DO NOT open or mutilate the battery or batteries. Released electrolyte is harmful to the
skin and eyes. It may be toxic.
A battery can present a risk of electrical shock and high short circuit current. The following
precautions should be observed when working on batteries :
1) Remove watches, rings, or other metal objects from the hands.
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 battery terminal.
Servicing of batteries should be performed or supervised by personnel knowledgeable of
batteries and the required precautions should be taken. Keep unauthorized personnel
away from batteries.
When replacing batteries, replace with the same number of the sealed lead-acid batteries.
The socket-outlet shall be installed near the equipment and easily accessible.
With the installation of the UPS, it should be prevented that the sum of (UPS and) the
connected (load) leakage current exceeds 3.5mA.
This pluggable type A equipment with battery installed by the supplier is operator installable
and may be operated by laymen.
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 connectors of the
battery when maintenance or service work inside of the UPS is necessary.
