Et 200S I/O Modules - Siemens SINAMICS G120 Function Manual

Components in separate control cabinets
If the components are located in separate control cabinets, the wiring between the SM326
I/O module and the F-DIs on the inverter must be installed such that it is protected against
cross and short-circuits.
Transfer the two signals for activating a safety function via wires in separate lines. In the
example, the signals for terminal 5 and 7 are transferred via the first line. The signals for
terminal 6 and 8 are then transferred via the second line.

ET 200S I/O modules

Fail-safe outputs that switch to P potential are required for activating the fail-safe digital
inputs of the SINAMICS G120. Out of the ET 200S system range, only the fail-safe relay
module EM 1 F-RO DC 24 V / AC 24...230 V / 5 A fulfills this requirement.
The fail-safe relay module is activated via a fail-safe ET 200S output module.
The diagrams only show how the I/O modules and inverter are interconnected. Information
providing full details of how the I/O modules is wired can be found in the product-specific
documentation: ET 200S
