The style of cover depends, it’s just for reference only.

1.1 “Power On” Indicator

Power On indicator illuminates when utilities’ power is normal. The indicator also
illuminates per each 4 seconds under Backup mode. Rapid flash (1 sec) means the
inner battery should be replaced again.
Attention: The internal battery have to be replaced when rapid flash occurred under
AC mode.

1.2 Outlets Design for AC Adapters

Allows two AC power adapter blocks to be plugged into the UPS without blocking

adjacent outlets.

1.3 Battery Power-Supplied Outlets

Provide instantaneous back-up power and full-time bypass protection to your
equipment. Ensure temporary uninterrupted operation of your equipment during
power failure.

1.4 Full-time Bypass Protection Outlets

Provides full-time Bypass protection to your equipment. Prevent surge from traveling
through your system through unprotected peripherals.

1.5 Power button(ON/OFF/TEST/SILENCE)

The UPS can be automatically turned on while connect to the utility power. After the
UPS is turned on, it conducts a self-test and enter normal mode. Press the power
button for 1 second under normal mode would also enable the self-test function
again. The silence function can be enabled/disabled by pressing the power button
for 1 second under backup mode.
In addition, Power button can be used as the master on/off switch of your equipment
by leaving your equipment connected to UPS and switched on. To turn off the UPS,
please press power button until buzzer stops (about 2 seconds).

(RS232 connector only for model with “S” suffix)

1.6 Circuit Breaker ( or Fuse)

Serves as an overload and fault protection. This is a critical component of the
advanced UPS surge protection circuit.

1.7 “Phone Jack” Communications Protection Ports (Option)

UPS’s exclusive communication protection ports will protect any standard modem,
PBX System or 10 Base T connection ports.

NSTALLATION

2.1 Recharge the battery

UPS may be used by anyone immediately upon receipt. The battery is fully charged
before shipped from the factory. However, user is recommended to recharge the
battery at least four hours before using UPS. Energy loss may occur during shipping
or long duration storage. To recharge the battery, simply let UPS be plugged into an
AC outlet and switch it on.

2.2 Connect the loads

Plug your primary equipment (e.g. computer, monitor and critical data storage
device, etc.) to the Battery backup outlets. Plug your peripheral equipment (e.g.
printer, scanner, fax, or audio device) to the Full-time Bypass Protection outlets. Do
not plug laser printer to the UPS, as its power demand is much higher than typical
peripherals and may cause the circuit breaker (or fuse) to trip.

2.3 Connect the telephone

If you wish to protect a fax or a modem, connect the telephone cable from the wall
outlet to the “IN” jack. Connect the telephone cable (provided) from the “OUT” jack
to the fax or modem. To protect a10/100Base-T (UTP) network interface, obtain and
use a UTP cable to connect the “OUT” jack to your computer.

2.4 Connect to the utility power

Plug UPS to a 2-pole, 3-wire grounding receptacle. Make sure the battery supply
outlets of the UPS do not service equipment requiring heavy electricity (e.g.
refrigerator, air conditioner, copier, etc.).

Attention:

When using extension cords, make sure the total rating of the loads is

suitable.

‘

2.5 UPS self-test

UPS will conduct a self-test once switched on it each time. Besides this, switch on
your equipment after switch on UPS. This function is disabled while buzzer is
alarmed caused by full (over) loads.

2.6 Battery auto-charging

The internal battery would be charged by charging circuit automatically, while utility
power is connected to the unit,

2.7 Auto restart feature

UPS would shut-down while battery voltage is too low, and wake up automatically
when utility power is normal.

D:\manual\UM_PCM-WOW\UM_WOW-300(S)\661-WOW3-000-31.doc

2.8 Overload protection

AC Mode: If load exceeds 100% of nominal rating, buzzer is keeping beep.
Backup Mode: UPS automatic shutdown, if overload exceeds 110% of nominal
rating at 1 sec.

2.9 Optimal battery status

To maintain the optimal battery status, leave UPS plugged in and switched on at all
time.

2.10 No load Shutdown feature

UPS is equipped with no load shutdown function. While no loads are connected to
the UPS, the unit will automatically shutdown after an hour.

3. O

PERATION

3.1 Simple test

It is recommended that the user perform a simulation test when using UPS for the
first time or when adding an additional piece of equipment. Conduct a
simulation-test: first, switch on UPS and wait for the power indicator to light up, then
simply unplug UPS to simulate the event of utility failure.

3.2 Check the power requirement of your equipment

3.2.1. Make sure the total power of your equipment does not exceed rating capacity.

3.2.2. Also make sure the equipment you plugged into the Battery Power-Supplied
outlets does not require total power exceeding the capacity of the UPS. Otherwise,
overload may occur and cause the circuit breaker to trip. If the power requirement of
your equipment differs from VA, convert the requirement power into VA by doing the
calculations below:

3.2.3. If the power requirement of your equipment is listed other than VA, convert the
requirement into VA by doing the calculations below.

Watt (W) X 1.81 = VA

3.3 Limited rating power of UPS

When utility power failure occurs, the battery power outlets will supply power to your
equipment from its battery. The buzzer will beep once every 4 seconds. Be sure that
your equipment is running under the limited rating power. To restore the battery
power by plugging UPS back in to the existing power source. Perform the self-test to
make sure UPS works properly.

OFTWARE AND COMPUTER INTERFACE (OPTION

)

4.1 Power Monitoring Software

The UPSMON series software (or other power monitoring software) is applied
standard RS-232 interface to perform monitoring functions, and then provides an
orderly shutdown of a computer in the event of power failure. Moreover, UPSMON
displays all the diagnostic symptoms on monitor, such as Voltage, Frequency,
Battery level and so on. The software is available for DOS, Windows 3.1x, Windows
95/98/2000/me, Windows NT V3.5 or later, Novell Netware and others. Call your
dealer for more information on computer OS compatible solutions.

4.2 Interface Kits

A series of interface kits is available for operation systems that provide UPS
monitoring. Each interface kit includes the special interface cable required to convert
status signals from the UPS into signals which individual operating system
recognize. The interface cable at UPS side must be connected to REMOTE PORT,
at computer side can be either COM 1 or COM 2. The other installation instructions
and powerful features please refer to READ.ME file.

CAUTION:

Use only factory supplied or authorized UPS monitoring cable!

4.3 The characteristics of computer interface port

The computer interface port has the following characteristics:
The communication port on the back of the UPS may be connected to host
computer. This port allows the computer to monitor the status of the UPS and
control the operation of the UPS in some cases. Its major functions normally include
some or all of the following:
To broadcast a warning when power fails.

ATTERY MAINTENANCE AND REPLACEMENT

5.1 Battery maintenance

For the preventive maintenance, keep the area around the UPS clean and duty-free.
Please also keep the UPS at ambient temperature of 25℃ (77℉). It is recommend
that the batteries charge for 24 hours after long storage.

5.2 Battery replacement

The battery should be replaced within 30 to 90 days if the Power-on indicator
flashes. To verify that the batteries need to be replaced, conduct a self-test by
pressing Power button. If the Power-on indicator continues to flash, please replace
the inner battery according to the follow procedure.

Battery Replacement Procedure

5.3 Storage

To store UPS, cover it and store it with the battery fully charged. During extended
storage, just connect the utility power to recharge the battery every three months to
ensure battery life.
