3.1 Switch on:
While utility input is connected to the UPS, press the "ON" button and keep
pressing over than 0.5 second. After that, connect the electrical cords of the
equipment that is going to be used such as computer or monitor with the terminal
on the rear panel of UPS.
Don't overload the machine with all the equipment used. The buzzer will beep continuously
to indicate overload status. UPS will shut down automatically to protect the machine.
Attention
: If the power of UPS isn't supplied by utility but by the internal batteries to
engage the UPS, press the "ON" button and keep pressing for over 3 seconds.
CAUTION
: Never connect a laser printer or plotter to the UPS with other computer
equipment. A laser printer or plotter periodically draws significantly more power than when
its idle status, and may overload the UPS.
3.2 Switch off:
By pressing and holding OFF button until the “LINE NORMAL” or “BACK UP” LED off.
3.3 Silence:
When UPS is under “BACKUP” mode, press “ON” button more than 1 second to silence
the audible alarm. (The function is disable when UPS is under condition of “LOW
BATTERY” or “OVERLOAD”)
Note: At back-up mode, UPS can be automatically turned off if none of the connected loads
is operating.
3.4 Self-test:
Use the self-test to verify both the operation of the UPS and the condition of the battery. In
normal utility power, push the ON/TEST button more than 1 second and UPS performs a
self-test function. During the self-test, the UPS operates a back up mode.
Note: During the self-test, the UPS briefly operates the loads on-battery (the on-battery LED
comes on).
If the UPS passed the self-test, it returns to line-interactive operation. The on-battery LED
goes off and the line-interactive LED goes on steadily. If the UPS is failed to pass the
self-test, it returns to line-interactive operation and lights the replace battery LED. The loads
are not affected. Recharge the battery overnight and perform the self-test again. If the
replace battery LED is still on, ask our nearest dealer to replace battery.
3.5 Load bar graph:
The 5-LED display shows the power drawn from the UPS by load. The display indicates the
percentage of the UPS‘s rated capacity. For example. If three LEDs are lit, the load is
drawing between 50% and 67% of the UPS’s capacity. If the UPS is overloaded, the
overload LED lights and alarm sounds.
3.6 Battery charge bar graph:
The 5-LED display shows the present charge of the UPS‘s battery as a percentage of the
battery capacity. When all five LEDs light, the battery is fully charged. When only two LED
lights, the battery can supply less than two minutes of run time for the load.
3.7 Cold start:
