NOTICE
NOTE
„Basic insulation" against SELV voltage of the control. A system voltage (Phase – PE) of
300 V is defined. Consequently, the connected sensors also must have a „basic insula-
tion" to the mains potential (e.g. motor winding)!

For control board APPLICATION and COMPACT.
➃
The voltage to the control of a brake is decoupled from the
internal voltage supply. The brake works only with external
voltage supply.

The brake can be supplied with both, internal and external
voltage. Voltage tolerances and output currents vary for
internal and external voltage supply..

KTY sensors are polarized semiconductors and must be
operated in forward direction! To this connect the anode
to TA1 and the cathode to TA2! Non-observance leads to
incorrect measurements in the upper temperature range.
A protection of the motor winding is then no longer guaran-
teed.
No protection of the motor winding in case of wrong connection.
► Operate KTY sensors in forward direction.
► KTY sensors may not be combined with other detections.
More information about the wiring of the temperature monitoring and the brake
control are described in the respective control unit manual.
