• Control terminal (Inputs/Outputs)
• The Powerdrive MD Smart inputs are configured in positive logic. Associating a variable speed drive with a
different command logic automator can cause the motor to start inadvertently.
• The control circuit of the Powerdrive MD Smart is isolated from the power circuits by a simple isolator. Its
electronic 0V is connected to the connection terminal of the external protection conductor (earth terminal).
The installer shall ensure that external control circuits are insulated against human contact.
• If the control circuits are to be connected to circuits complying with the SELV safety requirements,
additional insulation shall be inserted to maintain the SELV classification (see EN 61140).
