Example of the wiring of the S2M port for two OpenCom 130 / 150s
On the OpenCom 150 the pressure terminal is a 5-pin connector. The additional terminal is used to connect the shielding of a shielded line. The shielding has to be stripped as short as possible (approx. 3 mm).
6. If necessary, check to make sure that the NT is fed by its own power supply.
