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 once the failure (overload) is over). 
4.2 Disconnection of discharged battery. 
The PSU is equipped with the discharged battery disconnection system. During the battery-assisted operation, reducing 
voltage below 38V 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.  In  case  of  fuse  replacement,  use  a 
replacement of the same parameters.
