8.2 Motor Connection according to European Standard (EU)
Fig.8-4: Connection overview MKE according to European standard
The connection of the MKE motors, according to European standard, consists
of the following components:
● Power connector (incl. connection for temperature sensor and holding
brake)
● Encoder connection
● Additional outside connection for an equipotential bonding conductor (ac‐
cording to EN 50014: 1992)
Power and encoder connection
The power and the encoder cables have to be lead together with the EExd cable
duct into the terminal box and to be connected there with the plug-connector
and the screw-terminal.
Protection or equipotential bonding
conductor
The connection of the protective conductor terminal is to be made over the
power cable in the protective conductor into the terminal box of the MKE motor.
An additional connection of a protective or equipotential bonding conductor is
prescribed for MKE motors according to EN 50014: 1992. All MKE motors have
to be grounded over the additional connection part (protective conductor clamp
