Wiring Examples According To Sil 2 And Pl D - Siemens Sinamics G120 Function Manual

Installing
4.4 Controlling via a fail-safe digital input
Special requirements placed on EMC-compliant installation
Use shielded signal cables. Connect the shield at both conductor ends.
In order to connect two or more inverter terminals, use the shortest possible jumpers directly
at the terminals themselves.
Bright and dark test
The inverter filters signal changes using bright and dark tests at the fail-safe digital input using
an adjustable software filter.

Wiring examples according to SIL 2 and PL d

Examples for wiring the fail-safe digital inputs corresponding to PL d according to EN 13849-1
and SIL 2 according to IEC 61508 are provided on the following pages.
In order to reduce the scope of the examples, not all of the SINAMICS inverter types are listed
in each wiring example.
If, in an example, two or more terminals of the inverter are connected together, then you must
connect jumpers that are as short as possible directly at the terminals.
