1. Recommend Wiring
The interface has simply 3 signal wires for signal transmission.
• Use exclusively shielded twisted-pair cable to connect the device.
Comply with the maximum permissible connection cables length.
•
• Preferably connect the shield on both sides with low impedance to the protective earth (PE), e.g.on the device and/or on the evaluation unit. In the event of
potential differences, the shield must only be applied on one side.
