4. OPERATION
4.1.
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 LED is lit,
this will switch the UPS “On”. The UPS will perform self-testing each
time it is switched “On”.
4.2.
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.
4.3.
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.
During the self-test, the UPS briefly operates the loads with battery
power (the LED flashes every 2 seconds). If the UPS passes the self-
test, it returns to on-line operation. The LED stops flashing and the
LED remains on. If the UPS fails the self-test it immediately returns
to on-line operation. The loads are unaffected when performing a
s e l f-test. Recharge the battery overnight and perform the self-test
again. If the UPS still fails a self-test, ask our nearest dealer to
replace the battery.
4.4.
S ilence 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")
4.5.
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.
4.6.
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 sh utdown of protected servers.
