Figure 4-17 Connecting the modular safety system in separate electrical cabinets using SINAMICS
G120 with CU240E‑2 as example
For configurations and designs in separate control cabinets, route cables between the modular
safety system and the inverter so that they are protected against cross circuits and short
circuits.
If you wish to use the fail-safe digital outputs of the 3RK3 central module for a two-channel
signal transfer, then you must adapt the discrepancy monitoring of the inverter to the different
switching times of electronic output and relay contact.
