4. Operation and use.
4.1. Overload or short circuit of the PSU output.
The power supply outputs PoE, NVR are protected against short circuit by polymer fuses PTC. If the output
voltage value exceeds the acceptable threshold Imax (105% - 150% @25°C of the PSU power) there will be an
automatic disconnection of the output voltage. Disconnect the load from the power supply output for approximately 1
minute to restore output voltage (the time needed to cool down the PTC fuse).
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 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.
