The cable length between power supply and transmitter / receiver system is a maximum of 200 m.
A double insulated shielded cable with a minimum cross section of 0.75 mm² is recommended. From a cable
length of 100 m, the cable cross-section must be increased to 1 mm².
The transmitter / receiver system has an EMV cable gland. This serves for laying a cable shield. The shield
should only be placed on the connector in the transmitter unit is additionally fastened with the existing
