Notes on Installation
● Make sure the power supply for the motor holding brake at the motor is
sufficient. You have to take into account that voltage drops on the sup‐
ply line. Use connection 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 supplied at X6.n.
