SK 105E…175E Motor Starter Manual
30 Pre-series version BU 0135 GB-2713
2.6.2 Details of the SK 1x5E control connections
Control voltage 24V external! Terminal 44. If the motor starter is not equipped with an optional mains unit it
must be supplied with an external 24V voltage.
For devices with which the AS interface is used, the supply voltage can be taken from the AS interface cable
if the appropriate jumpers are set ("only yellow cable"). Otherwise the device can also have a separate
supply ("black and yellow cable"). In this case, the jumpers must not be set.

The motor starter generates an
output voltage on Terminals
MB+/MB- for control of an
electromagnetic brake. This
depends on the supply voltage to
the SK 1x5E.
It is essential to take the correct
brake coil voltage into account in
the selection.
