OPERATION
Switching “On” the UPS
With the UPS plugged in, and utility power present, press and hold the On/Off/Test/Silence Button
more than 3 seconds or until the "LINE NORMAL" LED is lit, this will switch the UPS “On”. The
UPS will perform a self-test every time it is turned “On”.
Note
:
When switched off, and still plugged into utility, the UPS maintains the battery charge and
will respond to commands received through the computer interface port.
Switching “Off” the UPS
Press and hold the On/Off/Test/Silence Button for more than 3 seconds, or until the Line Normal or
Back-Up LED turns off.
Self-Test
Use the self-test to verify both the operation of the UPS and the condition of the battery. When normal
utility power is present, push the On/Off/Test/Silence Button for less than 1 second and the UPS will
perform a self-test function. During the self-test, the UPS operates in back-up mode.
Note
:
During the self-test, the UPS briefly operates the loads with battery power (the Status LED
flashes). If the UPS passes the self-test, it returns to on-line operation. The Status LED stops
flashing and remains illuminated. If the UPS fails the self-test it immediately returns to on-line
operation and turns the Replace Battery LED on. The loads are unaffected when performing a self-
test. Recharge the battery overnight and perform the self-test again. If the Replace Battery LED is
still on, ask our nearest dealer to replace the battery.
Silence the Alarm
In Back Up mode, push On/Off/Test/Silence Button for less than 1 second to silence the audible alarm.
(The function is void when under condition of "LOW BATTERY" or "OVERLOAD")
Cold Start
When the UPS is off and there is no utility power, use the cold start feature to apply power to the loads
from the UPS's battery. Press the ON/TEST button (see Front Panel section for location of the
indicator) until the UPS beeps.
Shutdown Mode
In shutdown mode the UPS stops supplying power to the load, and waits for the return of utility power.
If there is no utility power present, external devices (e.g., servers) connected to the computer interface
can command the UPS to shutdown. This is normally done to preserve battery capacity after the
graceful shutdown of protected servers. The UPS will scroll the front panel indicators sequentially
when shutting down.
