5. Operation
__________________________________________________________
____
5.1 Switch on
With the UPS plugged in, press and hold the on/off/test/silence button more
than 1 second until "LINE NORMAL" LED lit to switch the ups on. The UPS
will perform self-testing each time when it is switched on.
Note: When switched off the UPS maintains the battery charge and will
respond to commands received through the computer interface port.
5.2 Switch off
By pressing and hold the on/off/test/silence button more than 3 seconds until
the "LINE NORMAL" or "BACK UP" LED off.
5.3 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/off/test/silence button less
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 passes the self-test, it returns to on-line operation. The on-
battery LED does off and the on-line LED goes on steady.
If the UPS fails the self-test it immediately returns to on-line 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.
5.4 SILENCE
In "BACK UP" mode, push on/off/test/silence less than 1 second to silence the
audible alarm. (The function is void when 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.
