USER MANUALME-650-VU/850-VU
ME-1000-VU/2000-VU
Thank you for purchasing this UPS. 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.
IMPORTANT SAFETY INSTRUCTIONS
This UPS utilizes voltages that may be hazardous. DO
NOT attempt to disassemble the unit. The unit contains
no user serviceable parts. Only factory service
personnel may perform repairs.
Internal battery voltage is 12VDC.
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
locations 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 batteries terminals.
Servicing of batteries should be performed or
supervised by personnel knowledgeable of batteries
and the required precautions. Keep unauthorized
personnel away from batteries.
When replacing batteries, replace with the same
number and type of sealed lead-acid battery.
This pluggable type A equipment with battery already
installed by the supplier is operator installable and may
be operated by laymen.
During the installation of this equipment it should be
assured that the sum of the leakage currents of the
UPS and the connected loads does not exceed 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
connectors of the battery when maintenance or service
work inside the UPS is necessary.
The mains socket outlet that supplies the UPS shall be
installed near the UPS and shall be easily accessible.
