3. Cooperation with the MPSB48 automation module (option).
The MPSB48 automation module is intended for indicating the operating status of buffer power supplies, PSB 54V
type. The PCB board features LEDs that indicate PSU operating status (presence of AC voltage, presence of DC voltage,
battery voltage). The module is also equipped with technical outputs of: EPS - AC power loss, PSU - PSU failure, LoB -
low battery voltage.
Element no.

4. Maintenance.
All maintenance procedures can be performed after the disconnection of the power supply from the electrical grid.
The power supply does not require any special maintenance procedures, but in the case of significant dust accumulation,
dusting using compressed air is recommended.
