The shutdown for a motor overtemperature condition is achieved by safely shutting down the motor control pulses of the inverter - and not by disconnecting from the main power supply using a motor contactor.

    Appendix A.4 ATEX application A.4.3.2 Explosion-protected motors in hazardous zones Special rules and regulations apply - and which must be strictly observed - when operating motors in hazardous zones. Rules 1. The motor must be certified for the particular hazardous zone. The appropriate marking is stamped on the motor rating plate.

  • Page 91 Install the fail-safe control module (e.g. CU250S-2 DP) corresponding to the operating instructions of the SINAMICS G120 Control Unit. 24 VDC must be connected to the safety input terminals (5, 6 and 64) of the fail-safe control module via the TMS output terminals (the 24 V output of the inverter should be used for this purpose in order to avoid the formation of parasitic voltages).
  • Page 92 Appendix A.4 ATEX application Figure A-4 CU250S-2 DP connection area (fail-safe inputs/outputs are marked in yellow) In the case of an overtemperature, the TMS initiates a fault and shuts down the 24 V at the outputs. In the inverter, this triggers the parameterized STO safety function, which immediately inhibits the pulses.
