1. INTRODUCTION
1.1 Overview
The Value Series of Uninterruptible Power Systems (UPS) was designed to prevent
spikes, transients and blackouts from reaching your sensitive equipment. Your equipment
may include such items as computers and computerized instruments to
telecommunication systems. When AC power is present, the UPS filters the power
continuously. When AC power fails, the unit employs its internal maintenance-free battery
to supply back-up power without interruption.
1.2 Frequency Auto Sensing
The VS models can operate in either a 50 or 60 Hz environment. When you plug the UPS
into an AC outlet and turn it on, it will automatically detect the incoming line frequencyand
configure itself to match that frequency.
1.3 User Replaceable Battery Design
The battery is the most critical part in a UPS. The average lifetime of a battery is between
3 and 5 years. The special user-replaceable battery design of this UPS provides
significant savings and gives the UPS an almost unlimited life. You can replace the battery
very easily, and without turning off your UPS or the equipment it is protecting.
Many UPS’s provide only a basic power failure warning. The Value Series, together with
OPTI-SAFE Xtreme also provides you with important operating information. If OPTI-SAFE
Xtreme is not part of your UPS package, you can purchase it from your local dealer.

6VS375C/VS575C
1.4 Over Voltage and Under Voltage Protection
The UPS will switch to backup mode and provide the power from its internal battery when
the input line voltage is too low or too high.
1.5 Schedule Shutdown & Startup
Using OPTI-SAFE Xtreme you can locally or remotely control the shutdown and startup of
equipment connected to a UPS. A customized schedule can be developed to meet your
specific requirements.
1.6 Data-Line Surge Protection
The built-in data-line surge suppression on the rear panel completes your system
protection. It provides an easy way to protect a network (RJ45) or modem (single line
phone) connection from hazardous spikes.

2. UPS CONTROLS
2.1 External Views
2.2 Power On/Off/Test/Silence Button:
The On/Off/Test/Silence Button has four functions:
1. When the UPS is off and AC power is present, press this button for more than 3
seconds to turn on the UPS. The UPS can be turned on even when AC power is
not present.
2. When the UPS is on, press this button for more than 3 seconds to turn off the
UPS and output power.
3. When the UPS is operating in “Battery” mode, you can silence the alarm by
quickly pressing the power button. (This function is disabled when the UPS has
a “LOW BATTERY” or “OVERLOAD” condition).
4. Quickly press the button while the UPS is under “AC” mode, and the UPS will
perform an automatic self-test procedure.
* “No load shut down” function: As a battery saving feature, the UPS will
automatically turn off if none of the connected equipment is operating while the
UPS is in back-up mode. Once normal utility power returns, the unit will wake up
automatically.
2.3 Status Indication
UPS Status Indication: Front Panel LED

8VS375C/VS575C
AC Mode When this Green LED is lit, the UPS is in normal mode, and providing power to your equipment. The UPS will
continue to filter and provide surge protection.
Battery Mode When this Yellow LED is lit, the UPS is providing power from its battery. Also, this LED is lit when you press the
button to test the battery.
Battery Fault
This Red LED indicator indicates twostatuses of the UPS:
When this Red LED is on, it indicates that the battery
needs to be replaced. When this Red LED is flashing
rapidly, it indicates the UPS is over loaded.
2.4 Communication Port (Remote Port)
This port allows for a computer to monitor the status and control the operation of the UPS.
Its functions include the following:
♦To broadcast a warning when power fails.
♦To close any open files before the battery reserves are exhausted.
♦To turn off the UPS.
*Note that software and the communication cable are only available in certain areas.
Contact your local dealer for more information.
2.5 Data Line Surge Protection (In & Out)
The data line surge protection on the rear panel provides an easy way to protect a network
(RJ45) or modem(RJ11) connection from hazardous spikes. Connect a network cable or a
single line telephone into the “In” socket. To complete the connection, connect another
network cable or telephone line into the “Out” socket.
2.6 AC Input
Connect the AC power cord into the AC Input socket. UPS can have power from
commercial electricity. It has a fuse in the socket to protect over current. The spare fuse
also inside the socket for replacing.
2.7 Output outlet
There are two kinds function output outlets:
1. Bypass : These output outlets offer surge protection only. It won’t have back up
power at inverter mode.
2. UPS outlet : These output outlets not only offer surge protection but also back up
power to your main equipments at inverter mode.

3. INSTALLATION AND OPERATION
Before installation, please read and understand the following instructions:
3.1 Unpacking and Inspection
Examine the packing carton for damage and accessory in the box. Notify the carrier
immediately if damage is observed.
* UPS *1
* User Manual *1
* Power Cord *1
* CD-ROM *1
* Communication Cable *1
* Telephone Line *1
3.2 Placement
1. This unit is intended for indoor use only. Although your UPS is very rugged, its
internal components are not sealed from the environment.
2. The UPS must be installed in a protected environment away from heat-emitting
appliances such as heaters or radiators. Do not install this product where excessive
moisture is present.
3. The location should provide adequate air flow around the UPS with one inch
minimum clearance on all sides for proper ventilation.
3.3 Determining How Much Equipment You Can Connect to Your UPS
1. Make a list of all equipment that requires protection.
2. Each piece of equipment has voltage and current (VA) ratings printed on the back
label (see examples below). Your equipment may have a voltage rating such as 88-
264V. If you live in the United States you should use 120V in your calculations,since
the standard voltage in the United States is 120V.

120V 2.0A
50/60 Hz
SN: 123456
3. Multiply the voltage and current of each piece of equipment (VA requirements); for
example, 120V x 2.7A = 324VA, 120V x 2.0A = 240VA.
Add up the VA requirements for all the devices; for example, 324VA + 240VA =
564VA.
4. Make sure that your UPS has at least as much VA capacity as your equipment
requires.
3.4 Powering Up Your UPS
1. For 100/110V/120V versions, connect the power cord to a grounded 3-wire
receptacle. For 220V/230V/240V versions, please refer to Sec 3.5 .
2. Power up the UPS by pressing the On/Off switch on the front panel for three
seconds.
3. We recommend that you charge the battery for six (6) hours before first use of your
UPS. You may use the UPS immediately without charging the battery, but the
backup time may be less than the rating. The UPS recharges the battery
automatically whenever AC power is available.

VS375C/VS575C 11
3.5 Connecting Your Equipment to the UPS
1. For all UPS models except the 2x0V versions: connect the power cord(s) of your
computer equipment to the output receptacle(s) of the UPS. Switch on the computer
equipment.
2. For 2x0V versions, as shown in the illustration below: connect the input power cord
of your computer equipment to the inlet of the UPS and the wall socket. Use the
power cord supplied with the UPS to connect from the outlet of the UPS to your
equipment. Switch on the computer
3. DO NOT PLUG LASER PRINTERS INTO THE UPS BECAUSE THEY TYPICALLY
DRAW TOO MUCH POWER
3.6 Operation and Function Test
1. Connect the input power and turn on the UPS. The front panel Normal Mode LED will
light.
2. The UPS may be overloaded if the UPS buzzer sounds continuously and the Battery
Fault LED flashes. Unplug the least critical devices, such as a printer, etc. If the
buzzer is still sounding, the battery or UPS may be faulty. Contact your local dealer
for assistance.

12 VS375C/VS575C
Note: Backup all unsaved files before you perform the following functional test.
3. To test the backup function, you may unplug the power cord of the UPS. During this
test, observe that your equipment operates properly and without interruption. If you
leave your UPS on continuously, it is a good idea to perform a backup function test at
least once a month.
4. If you unplug the power cord, all models will beep once every 4 seconds and the
Battery Mode LED will light. You can press the Test/Silence Button to silence the
alarm. Plug the power cord back in after a few seconds.
3.7 Storage Instructions
For extended storage in moderate climates, the battery should be charged for 12
hours every 3 months. Repeat it every 2 months in high temperature locations. Plug
in the power cord to charge the battery.
