Important Safety Instructions
Ÿ The voltages inside UPS may be
hazardous. Do not attempt to disassemble
the unit. The unit contains no user
serviceable parts. OnIy factory service
personnel may perform repairs.
Ÿ Internal battery voltage is 12VDC, 7Ah.
sealed, lead-acid, battery x1no.
Ÿ Connection to any other type of socket
other than a two-pole, three-wire grounded
socket may result in shock hazard as well as
violating to local electrical codes.
Ÿ 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 external
objects to enter the UPS. Do not place
beverages or any other liquid-containing
vessels on or near the unit.
Ÿ This unit is designed for installation in a
controlled environment (temperature
controlled, indoor area free of conductive
contaminants). Avoid installing the UPS in
locations where there is static or flowing
water, or excessive humidity.
Ÿ Do not plug the UPS input into its own
output.
Ÿ Do not attach a power strip or surge
suppressor to the UPS.
Ÿ Do not connect non-computer-related
items, such as medical equipment, life-
support equipment, microwave ovens, or
vacuum cleaners to UPS.
Ÿ 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 air heaters or furnaces.
Ÿ Unplug the UPS prior to cleaning and do
not use liquid or spray detergent.
Ÿ Do not dispose the batteries into 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.
Ÿ A battery can present a risk of electrical
shock and high short circuit current. The
following precautions should be observed
when working on batteries:
a) Remove watches, rings, or other metal
objects from the hands.
b) Use tools with insulated handles.
c) Wear rubber gloves and boots.
d) Do not lay tools or metal parts on top
of batteries.
Ÿ Disconnect charging source prior to
connecting or disconnecting batteries
terminals.
Ÿ Servicing of battery should be performed
or supervised by technical and authorized
personnel only.
Ÿ When replacing battery, replace with the
same type of sealed lead-acid battery. The
maximum ambient temperature rating is
40°C.
UPS Installation Procedure
Ÿ Your new UPS may be used immediately;
however recharging the battery for atleast
8hours (no load) is recommended to ensure
that the battery maximum charge capacity is
achieved. Charge loss may occur during
shipping and storage.

To recharge the battery, simply leave the unit
plugged into an AC outlet. The unit will
charge in both the on and off position.
Ÿ With the UPS unit off and unplugged,
connect the computer, monitor, and any
externally powered data storage device (Zip
drive, Jazz drive, Tape drive, etc.) into the
battery power supplied outlets. DO NOT plug
laser printer, copier, space heater, vacuum,
paper shredder or other large electrical
device into the battery power supplied
outlets. The power demands of these devices
will overload and possibly damage the unit.
Ÿ Plug the UPS into a 2 pole, 3 wire
grounded socket (wall outlet). Make sure the
wall branch outlet is protected by a fuse or
circuit breaker and does not service
equipment with large electrical demands (e.g.
air conditioner, refrigerator. copier, etc. Avoid
using extension cords.
Ÿ Press the power switch to turn the unit
ON. The power on indicator light will
illuminate and the unit will "beep".
Ÿ If an overload is detected, an audible
alarm will sound and the unit will emit beep
once every 0.5 seconds. To correct this turn
the UPS off and unplug atleast one piece of
equipment from the battery power supplied
outlets.

Wait 10 seconds Make sure the fuse is
normal and then turns the UPS on.
Ÿ To maintain optimal battery charge, leave
the UPS plugged into an AC outlet at all times.
Ÿ To store your UPS for an extended period,
cover it and store with the battery fully
charged. Recharge the battery every three
months to ensure battery life.
