3. OPERATION
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 terminalon 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 (See section 2.8 for location of the indicator on
the front panel) 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
