USER’S MANUAL
To ensure that your computer equipment will be protected during a utility failure and that you receive expected run time, it is important
that you determine the total power needs of the equipment you wish to protect with the UPS. The power requirements of your equipment
should be less than or equal to the capacity of the UPS. The UPS will emit a loud tone and the yellow LED will illuminate to alert you of
the overload. Consult your dealer for the power requirement of your equipment. Once you have determined that your equipment and the
UPS are compatible, plug your equipment into the UPS’s real panel output receptacles.
5. Test for proper operation
Turn on the UPS’s power I/O switch and switch on your computer equipment. The green NORMAL indicator at the front panel should be
illuminated and your equipment should operate normally.
To test the operation of the UPS, simply unplug its input cord to simulate a utility blackout. The UPS will immediately transfer your equip-
ment loads to power derived from the UPS’s internal battery. During this time, the UPS will emit a beep once every 10 seconds and green
LED blinking to remind you your equipment is operating from a source of power that is limited in duration. Restore power to the UPS by
plugging in the line cord. Repeat this test four or five times to ensure proper operation.
Another way to test the operation of the UPS, simply press and hold the ON/OFF/TEST button for 4 seconds and 4 beeps of alarm and
then release it to run a 10-second self-test routine. The UPS will transfer your equipment to power derived from the UPS’s internal bat-
tery and run self-test. See the following section if abnormal operation is encountered.
6. Overloads & output shorts
If the total power requirement of your equipment is much greater than the capacity of the UPS, the UPS’s rear panel circuit breaker may
trip. Once the breaker is tripped, the UPS will attempt to operate the load using its internal power source and emit a loud tone before the
UPS shuts down and ceases to power your equipment. The yellow led will illuminate and stay on to alert you of the overload till the UPS
starts up again. In this case, turn off the UPS and decide which equipment will be left unprotected by the UPS. Find the input circuit break-
er on the rear panel and reset the breaker by pressing the plugger of the breaker after the overload or short circuitry is released. Then
start up the UPS again. Do not plug laser printers over 1000W into this UPS. The power requirement of a laser printer is much larger than
the capacity of this UPS.
7. Connect Telephone/Network Surge Suppression
Connect a single line telephone or a 10Base-T network cable into the telephone/network surge protection sockets on the back of the UPS.
The RJ-45/RJ-11 modular combination sockets accept all standard single line telephone and 10Base-T connections. The cable coming
form the telephone service or networked system is connected to the port marked «IN», the «OUT» port is connected to the equipment to
be protected.
