4.2.3 Set NO LOAD SHUTDOWN switch (special optional) to ON position to shutdown UPS
automatically when power fails and all connected loads are less than 60 W in order to
save battery power. (This optional switch is set at OFF position as default from factory)
If the connected load is PABX which consumes power less than 60 Watt, set the switch
to OFF position.
Note:
For the standard product which does not have the NO LOAD SHUTDOWN
switch at the rear side of the UPS, UPS has built-in this features. It will auto-
matically shutdown when power fails and detects that connected loads are
less than 60 Watt.
4.2.4 Plug in the electrical appliances such as computer, monitor, modem, fax machine, etc.
to the UPS OUTPUT outlets at the rear side of the UPS.
4.2.5 Plug in the laser printer to the “FOR LASER PRINTER” outlet which is connected to surge
protection system. (This socket does not supply backup power when power fails)
4.2.6 Plug in the AC INPUT power cord to the utility line.
4.2.7 Turn on the POWER switch of the UPS and then turn on all connected loads.
4.2.8 Test the UPS after the battery is charged by turn on POWER switch and wait until the
LINE indicator is lit. Then, turn on all connected loads. To simulate blackout situation,
unplug AC INPUT power cord from utility line, UPS will supply backup power to loads
automatically. The ALARM indicator blinks slowly and alarm sounds simultaneously.
Then, plug the AC INPUT power cord back to utility line. The ALARM indicator is off,
no alarm sound and the LINE indicator is lit. Notice that all connected loads are still
operating during test. For more confidence, repeat the test for 3-4 times.
4.2.9 After finished work with the computer, shut it down and turn off the UPS to keep
sufficient battery power is available when there is blackout.
4.2.10 If you have to storage UPS for long period of time, be sure that battery is fully charged
and it need to be recharged every three months to preserve the condition of the
internal battery. Only connect the UPS to utility line and turn on, then leave the UPS
connected to utility line for at least 8 hours.
