4.2 Running the PSU from the battery.
The power supply is equipped with the button on the PCB allowing to run the PSU from the battery, when
needed. To do that, press and hold the
START
button on the unit board for 1 second.
4.3 Deep discharge battery protection UVP.
The power supply is equipped with deep discharge battery protection (UVP). If the voltage at the battery
terminals drops below 1
0V±0.5V during battery-assisted operation, the batteries will be disconnected.
The battery
protection is on when the P
BAT
jumper is off.
Caution.
It is not recommended to disable UVP since deep discharge of the batteries reduces their ability to
store energy, their capacity and lifetime.
4.4 Maintenance.
All maintenance procedures can be performed after disconnecting the power supply from the power
network. The PSU does not require any specific maintenance; however, its interior should be cleaned with
compressed air if used in dusty conditions. In case of fuse replacement, use only compatible replacement parts.
