The filter times to debounce terminals X21.3 and X21.4 are set using parameters (see
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".
Danger to life due to 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
