The figure below shows the main and control circuit wiring.
Wiring sequence should shut off
power to the drive when a fault

<1> Remove the jumper when installing a DC reactor. Models CIMR-L20085 through 20415 and 40045 through 40216 come with a
built-in DC reactor.
<2> The drive provides a stop function in compliance with Stop Category 0 (EN 60204-1) and "Safe Torque Off" (IEC/EN 61800-5-2). It has been
designed to meet the requirements of the ISO/EN 13849-1, Category 3 PLd, and IEC/EN 61508, SIL2. Using this function the number of motor
contactors can be reduced to one. Refer to
<3> Never short terminals SP and SN, as doing so will damage the drive.
<4> Disconnect the wire jumper between H1-HC and H2-HC when utilizing the Safe Disable inputs.
Note: 1.
The drive should be implemented in the system in a way so that a drive fault causes the safety chain to open. Always use terminal
MA-MB-MC for this purpose.
2.
Even though no fault is present, conditions where the drive may not start can occur, e.g. when the Digital Operator is left in the
Programming Mode. Use the "Drive Ready" output (default set to terminals M5-M6) to interlock operation in such situations.
