4. Operation and use.
4.1. Overload or short circuit of the PSU output.
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. 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. In case of fuse
replacement, use a replacement of the same parameters.
