Description
X5 (X5), X6 (X6),
X7 (X7)
Interlock (potential-
free changeover
contact, common
contact on X5)
During braking, the contact between X5 and X6 is
open. This contact is to be looped into the control
circuit of the motor contactor. Therefore, the motor
cannot be started during braking.
The contact between X5 and X7 is closed during
braking. Thus, it is, e.g. in the case of star-delta-
connections, possible during braking to control the
star contactor in order to interconnect the motor
winding.
For more detailed information, please see connection
diagram on page 20.
(X10), (X11)
Fault signal
(potential-free
relay contact)
In case of a fault this concact opens. For closer
details on the tripping characteristics please see
chapter 5.2., page 7.
This contact is only available with the circuit-board
version.
