The active current loop option board can only be installed in the COM3 socket of the mainboard.
When IND256x is connected to ACM200, it is necessary to connect the ACM200 using the active
current loop to achieve communication in the safety area.
Customer-specific cables for intrinsically safe circuits must be customized as follows:
4. Cut the cable to length and strip the cable ends according to dimension A/B.
5. Shorten cable shielding on both sides to 10 mm (0.4").
6. Strip wire ends.
7. Crimp wire end ferrules onto wire ends with a crimping tool.
8. Push second rear section of the earthing cable gland onto the cable.
9. Apply the cable shielding only to the IND256x end by pushing the sleeve over the wires and the
10. Push on front section of cable gland and screw it onto the rear section.
