IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS – This manual
contains important instructions for models
PowerMust 400 Offline, PowerMust 600 Offline,
and PowerMust 1000 Offline that should be
followed during installation and maintenance of
the UPS and batteries.

Safety – CAUTION!
This product is specially designed for PCs and it is not recommended
for use in any life-supporting system and other specific important
equipment.
CAUTION: Risk of electric shock, do not remove cover. No user
serviceable parts inside. Refer servicing to qualified service
personnel.
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 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 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 Aequipment 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.
Φon the rating label stands for phase symbol.
WARNING: This is a UPS Class C2. In residential subdivision the
product may cause harmful interference, then the users have to take
additional measures.”

2. Installation and operation
1. Inspection
Remove the UPS from its packaging and inspect it for damage that
may have occurred during shipping. If any damage is discovered,
repack the unit and return it to the place of purchase.
2. Charging
This unit is shipped from the factory with its internal battery fully
charged, however, some charge may be lost during shipping and the
battery should be recharged prior to use. Plug the unit into an
appropriate power supply then switch ON the UPS and allow the UPS
to charge fully by leaving it plugged in for at least 10 hours with no load
(no electrical devices such as computers, monitors, etc.) connected
3. Placement
Install the UPS unit in a protected environment that provides adequate
airflow around the unit, and is free from excessive dust, corrosive
fumes and conductive contaminants. Do not operate your UPS in an
environment where the ambient temperature or humidity is high.

4. Computer Connection
Plug the UPS into a 2-pole, 3-wire grounded receptacle. Then connect
one computer-related device into each of the power receptacles
supplied on the back of the UPS.
5. Modem/Phone Line Connection
Plug incoming Modem/Phone line into the “In” socket at the back of the
UPS. Use another cable and plug one end to the “Out” socket at the
back of the UPS. Plug the other end to the modem input socket as
shown.
5. Turn On/Off
Press the switch of the UPS continuously for 1 second and the UPS
turns into its normal state (the green light is on and the beeper is off)
after it performs a self-diagnosis (the beeper and the red and green
indicator lights are on) for several seconds. At this time, user may turn
on the PC and other loads. Press the switch of the UPS continuously
for 1 second to turn off the UPS.
Note: 1. For the convenience of maintenance, please turn on the UPS first
before turning on the PC and the other loads, and turn off the UPS
after the loads are turned off.
2. At ordinary times, we recommend to remain the UPS on with the
battery charging (even if the loads are turned off), which is benefit
to the maintenance of the battery.
