11 Electrical connections
11.1 Overview of connections
The electrical connections of MKE motors include the following
components:
· a power connection includes a connection for temperature sensors
and holding brake, with single-wire design
· an encoder feedback connection with a standard encoder cable
design, and
· an additional external connector for a grounded conductor or for an
equipotential bonding conductor (according to EN 50014: 1992).

The power and feedback lines of MKE-UL/CSA motors enter the motor
through a special line duct. The approx. 1.5 meter long connection lines
must be guided through a ¾“ metal pipe into an approved Ex terminal
box; see Fig. 11.2. Standard connection lines lead from the Ex terminal
box to the drive controller.
