Dangers relating
to the software:
It is the responsibility of the employer to ensure that the safety
measures (such as the direction of rotation protection) and the
resulting action (such as the stoppage of the pump) are
appropriately included in the safety circuit.
To check the direction of rotation the motor must be briefly switched on. The motor may then not reach
operating speed. With an incorrect direction of rotation the connection on the terminal board must be
changed.
