Connection overview according to American standard
The connection of the MKE motors, according to American standard, consists
of the following components:
●
a power connector, incl. connection for temperature sensor and holding
brake, single-wire construction
●
encoder connection, standard-cable construction
●
additional outside connection for an equipotential bonding conductor (ac‐
cording to EN 50014: 1992)
Power and encoder connection
The connection cable of the MKE motors are to be realised through a special
cable duct into the motor. The ca. 1.5 m long connection cables have to be led
through a ¾ inch metal pipe into an approved Ex terminal box (see
Connection variants MKE motors" on page 65
). Standard connection cables
lead from an Ex terminal box to a drive control device.
