PowerWalker VI 750R User Manual
1. INTRODUCTION
This series is a compact and fully pure sinewave line interactive UPS, and it
designs for critical application and environment, such as desktops, servers,
workstations, and other networking equipments. This model is available in the
output ratings of 750, 1000, 1500, 2000, and 3000VA. This series protects
your sensitive electronic equipments against power problems including power
sags, spike, brownouts, line noise, and blackouts.
This series designs from two-in-one form factor; it can be placed either in
Rack 2U or Tower. The front panel of the UPS includes LED indicators and
four push buttons (Power Switch, UPS Test/Silence, Configure, and Enter)
that allow to monitor easily, configuration and control, AC line-in, notification
of site wiring fault and output load status of the UPS. It also includes four
LED bar graphic (Load/Battery Level Indication); two status indications (On
AC, On Battery); five alarm indications (Overload, Over Temperature, Site
Wiring Fault, Battery Fault, Self Test Failure). A push button from the front
panel allows silencing of the AC fail alarm and the initiation of the UPS self
test sequence as well. The UPS case for 750 ~ 2000VA is made of plastic as
well as 3000VA is made of metal.
This series is powered from the AC mains and supply AC outputs via
receptacles on the rear panel. Communication and control to the unit is
available through serial or USB ports located on the rear panel. The serial
port will support communications directly with a server. The communications
protocol for the serial ports shall conform to true RS232 interface.

2. SAFETY INSTRUCTION – CAUTION
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS - This Manual Contains Important
Instructions that should be Followed during Installation and
Maintenance of the UPS and Batteries.
WARNING: Do not attempt to repair and service this UPS. This UPS
contains high voltages which could cause the risk of electrical shock.
Even this UPS is disconnected from the electrical outlet, the dangerous
voltage still may be present through the battery. All maintenance and
battery replacement should be performed by qualified service
personnel only.
1. This UPS must be placed indoors with adequate airflow and free of
contamination. To install or operate it in a clean and indoor environment,
free from moisture, flammable liquids, and direct sunlight. Ambient
temperature range must be 0°C to 40°C (32°F to 104°F).
2. This UPS is designed for Commercial/Industrial use only. It is not
intended for use with life support application and other designated
“life-critical” devices.
3. Do not remove the input power cord when this UPS is turned on. This
removes the safety ground from this UPS and the equipment connected to
the UPS.
4. Turn off this UPS and disconnect input power cord before battery
replacement.
5. Battery contains high short-circuit current. Replacing or servicing the
battery which should be performed and supervised by qualified service
personnel knowledgeable of batteries and required precautions.
Remove watches and jewelries
Use tools with insulated handles
Wear rubber gloves and boots.
Do not lay tools or metal parts on top of batteries.
Disconnect charging source prior to connecting or disconnecting battery
terminals.

6. When replacing the batteries, use the appropriate replacement battery kits,
same number and type of battery are MUST.
7. Do not open or mutilate the battery. Released electrolyte is harmful to skin
and eyes that may be toxic.
8. Do not dispose of battery in a fire. Battery may explode. Proper disposal of
battery is required. Please refer to your local laws and regulations for
disposal requirements.
9. To reduce the risk of fire, use only No. 26 AWG or larger
telecommunication line cord.

2. SAFETY INSTRUCTION – CAUTION
10. This UPS contains high voltages which may cause the risk of electric
shock. Do not remove cover. There are no user replaceable parts inside
this UPS. Please contact your local dealer or distributor for service.
11. To reduce the risk of fire, connect to a circuit provided with 1.25(at least
20A) amperes maximum branch circuit over-current protection in
accordance with the National Electric Code, ANSI/NFPA.
12. This pluggable type A equipment with battery already installed by the
supplier is operator installable and may be operated by laymen.
13. 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.
14. 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 of the battery when maintenance
or service work inside the UPS is necessary.
15. The mains socket outlet that supplies the UPS shall be installed near the
UPS and shall be easily accessible.
