and Controls
The connection consists of an M6 thread and is used for mounting the shielding
plate for shield connection of the motor power cable (accessory HAS02.1).
The ground connection of the housing is used to provide functional safety of
the drive controllers and protection against contact in conjunction with the
equipment grounding conductor.
Ground the housings of the drive controllers:
1. Connect the bare metal back panel of the drive controller in conductive
form to the mounting surface in the control cabinet. To do this, use the
supplied mounting screws.
2. Connect the mounting surface of the control cabinet in conductive form to
the equipment grounding system.
3. For the ground connection, observe the maximum allowed ground resist‐
ance.
