Connection Diagram
The connection of the equipment grounding conductor can either be at
terminal connector X5 or directly at the drive controller (this figure
shows a terminal connector X5 with connection of the equipment
grounding conductor).

Notes on Installation
Make sure the voltage supply for the motor holding at the motor
brake is sufficient. You have to take into account that voltage
drops on the supply line. Use connecting lines with the highest
possible cross section of the single strands.
An external contact element is required, if motor holding brakes
with higher currents than the allowed current load are to be sup‐
plied at X6.
