System On command via battery (Cold Start)
For the COLD START button location, please refer to the “General views” chapter.
Note: Avoid turning on the system from battery if the battery charge status and/or the autonomy information are
unknown.
Close the battery fuse holders.
Press the “cold start” button and keep it pressed for at least 5 seconds.
The system will turn on in the “STAND-BY WITH CB OFF” mode (The status led will light up and the display
will start).
NOTE:
if no actions are taken within one minute, the system will automatically shut down to avoid discharging the
batteries.
Verify that no anomalies are present on the status bar (except for the anomalies referring to the absence of
input and bypass mains and the “Output Switch open”).
From the “Command Panel” page, press the “System ON” icon to start the System.
Confirm the “SYSTEM ON Command”, by selecting OK. The UPS will turn on.
If the battery measurements are ok and no anomalies are present except “Output Switch open” (the system
will be in the “DISCONNECTED FROM LOAD” state), close the SWOUT output switch.
Verify the output voltages on the Output status page.
The system is now in the BATTERY WORKING mode.
To restore the UPS to On Line mode, close the input (SWIN) and bypass input (SWBYP) switches with
mains present. The UPS will change to ON LINE mode and the batteries will begin to charge.
Operations checks
Follow the procedures below to verify that the UPS works properly during battery working and automatic bypass
switching. These operations must be executed with the UPS in ON LINE mode.
Battery Test
Press the “Battery Test” icon to execute the command. A
confirmation is required.
Wait until the procedure has been completed. Only if the
battery test result gives no anomalies, continue with the
Battery Working check.
Battery Working
Open the input switch (SWIN) and wait for a few seconds.
Check that the UPS goes into Battery Working status and
that the output voltage remains present and stable by
checking the system output page.
The buzzer should start to inform the user that the UPS is
running from battery.
