DANGER
Bypassing the protective device
The dangerous state may not be stopped in the event of non-compliance.
If T-connectors are used for the cascade, mount connecting cables in such a way that a
single T-connector (and therefore a safety locking device) cannot be jumpered easily.
NOTE
In the case of safety locking devices cascaded with T-connectors, the application diag‐
nostic output cannot be analyzed.
Cascade connection (M12, 5-pin)
The 5-pin male connector of the last T-connector before the safe evaluation unit is the
interface between the cascade and the safe evaluation unit.
