ET 200 I/O modules
Safety outputs that switch to P potential are required for activating the safety digital inputs of
the SINAMICS G120. From the ET 200 system range, only the fail-safe relay module EM 1
F-RO DC 24 V / AC 24...230 V / 5 A of the ET 200S system fulfills this requirement.
The relay module is controlled 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
(http://support.automation.siemens.com/WW/view/en/10805258/133300).
Components in the same control cabinet
A control cabinet that has been designed and wired correctly does not contain any damaged
wiring or cross circuits.
For this reason, you may interconnect the I/O modules and inverter in a control cabinet by
means of a single-channel wiring arrangement. The two terminals of the safety input must be
connected to each other at the inverter.
