4. Maintenance and operation.
4.1. Overload or short circuit of the power supply output (SCP activation)
In the case of short circuit or overload of the power supply, the F
AUX
fuse becomes permanently damaged.
Restoration of the voltage at the output requires fuse replacement
4.2. Protection against reverse battery connection.
The power supply unit is protected against reverse battery connection. In the case of incorrect connection
the FBAT fuse becomes damaged. The return to normal operation is possible only after replacing the fuse and
correct connection of the batteries.
4.3. Deep discharge battery protection (UVP).
The PSU is equipped with the discharged battery disconnection system. During the battery-assisted
operation, reducing voltage below 10V±1V at the battery terminals will disconnect the battery within 15 seconds.
Re-connecting the battery to the power supply occurs automatically once the 230V mains voltage is restored.
4.4. Battery test
The PSU performs the battery test every 5 minutes. During the test the power supply controller measures
the electrical parameters in accordance with the implemented measurement procedure.
A negative result occurs when the continuity of the battery circuit is interrupted, the resistance in the battery
circuit is above 300 mΩ, or when the terminal voltage drops below 12V.
The battery test is automatically locked when the power supply is in the mode in which performing the
battery test is not possible. Such a state occurs, e.g. during battery-assisted operation or in the case of power
supply overload.
4.5. The measurement of the resistance of the battery circuit
The power supply unit is fitted with a function that checks the resistance in the battery circuit. During the
measurement, the power supply controller takes into account the key parameters in the circuit and in the case of
exceeding the limit value of 300m Ohm it indicates failure.
A failure may indicate significant battery consumption or loosening of the connection cables.
4.6. Measurement of the battery temperature
The power supply unit is fitted with a temperature sensor to monitor the temperature parameters of the
installed battery.
The measurement of the battery temperature and the charging voltage compensation extend the battery life.
4.7. Maintenance.
Technical inspections and maintenance can be performed after disconnecting the power supply from the
power network
In the case of fuse replacement, use a replacement of the same parameters
Re-tighten all screw connections after 4 weeks from installation of the power supply. 2 [9.10].
