3.2 - Connection of the control
• The Powerdrive MD2S inputs have a positive logic
configuration. Using a drive with a control system which
has a different control logic may cause unexpedted
starting of the motor.
• The Powerdrive MD2S control circuit is isolated from
the power circuits by single insulation. Its electronic 0V
is connected to the connection terminal on the outer
protective conductor (earth terminal). The installer must
ensure that the external control circuits are isolated
against any human contact.
• If the control circuits need to be connected to circuits
complying with SELV safety requirements, additional
insulation must be inserted to maintain the SELV
classification (see EN 61140).
