Connect the Flexi Loop MSTR accessory to two outputs (X) and two safe inputs (I) of the
safety controller. Use 8-pin cables with M12 female connector and open cable ends to
connect the safe sensor cascade (
see "Pre-assembled cables", page 95
NOTE
If you connect the safe sensor cascade to the same power supply as the safety control‐
ler, then limit the current to 4 A.
Use both power supply pins (1 and 2) and both GND pins (5 and 6) on the MSTR Flexi
Loop accessory for the power supply.
