4. Operation and use. 

 
4.1 Overload or short circuit of the PSU output (SCP on) 
In case of overload, the output voltage is automatically shut off, and so is the LED indicator. The restoration 

of the voltage takes place immediately after the failure (overload) is over. 

 
4.2 Battery-assisted operation.  
In case of a main power outage, the device is immediately switched into a battery-assisted operation. 

 
 

 
The  PSU  is  equipped  with  the  discharged  battery  disconnection  system.  During  the 

battery-assisted  operation,  reducing  voltage  below  19V  at  the  battery  terminals  will  cause 
battery disconnection. 

 
4.3 Maintenance. 

Any and all maintenance operations may be performed following the disconnection of the PSU from the 

power supply network. The PSU   does not require performing any specific maintenance measures, however, in 
case of significant dust rate, its interior is recommended to be cleaned with compressed air. In case of fuse 
replacement, use a replacement of the same parameters.
