The filter times to debounce terminals X21.3 and X21.4 are set using parameters. You can find
additional information in the SINAMICS S120/S150 List Manual. Additional parameter settings
are also required in order to prevent discrepancy errors when performing bit pattern tests (light/
dark tests). For comprehensive information, see the SINAMICS S120 Safety Integrated Function
Manual, Chapter "Controlling the safety functions".
Electric shock when connecting unsuitable voltages
Touching parts and components that are at excessively high voltages can result in death or
severe injury.
• Only connect safety extra-low voltages (PELV/SELV) at terminals "EP +24 V" and "EP M1".
Temperature sensor
Electric shock when the motor temperature sensor insulation fails
When connecting temperature sensors which are not isolated from the motor power circuit in
line with safe electrical separation, arcing to the signal electronics may occur.
• Use temperature sensors whose temperature sensor has safe electrical separation.
• If safe electrical separation cannot be guaranteed (for linear motors or third-party motors,
