11.2 Survey of Interfaces
The connection of all inputs and outputs is made via the external connector on the Safety
Module. This is a S2L_36-connector (36 poles).
The following figure shows the internal and the external interfaces of the Safety Module
SAF-002 and SAF-003. The internal interfaces are connected to the controller’s
electronic.
They provide a safe access on the drive in case of request and the decoupling of a safety-
relevant signal of the controller in case of a demand mode and the decoupling of safety-
relevant controller signals, as e.g. encoder signals.
A description of external interfaces are in chapter

The different signal connection are described in the following.
11.3 External Interfaces
NOTE!
The physical inputs at the SAF module work on the closed current principle. That
means that a missing voltage at a safe input is always connected to the safety
function linked with this input.
A missing voltage at the safe input therefore is indicated as a "Low active input", as
the safety function is activated by this.
For instance, if the connecting cable attached to the SAF module was intentionally or
unintentionally removed or was torn off because a forklift truck drove over the cable,
the safety connected to the SAF module must be activated.
