Control input

Control terminals Designation
X3 (X1), X4 (X2)
Information on operation without connected starting contact:
The braking delay time (remanence time) may prolong itself by up to 50%.
The interlocking relay does not open immediately after the motor contactor has dropped out, but
only shortly before the braking relay closes. In contrast to an operation with connected starting
contact this means that the motor can be restarted during the braking delay time (remanence
time).
Caution: Danger to life through electric shock!
The terminals X3 (X1), X4 (X2) carry mains potential; when laying the
connecting lines, be sure to provide protection against accidental contact.
Starting contact
Description
Connection of a normally closed contact of the motor
contactor.
In standard applications not required.
Connection is only required, if more safety is required
(redundant system) to initiate braking.
