TABLE 6: M12 PIN ASSIGNMENT
Important note applicable to all Safetinex YBB models:
The same power supply must be used for the safety relay and both
AOPD units. If this is not possible and these devices are connected
to galvanically separated power supplies, then the 0V contact of the
AOPD units and the A2(-) contact of the safety relay must be bridged.
