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.
