Extension cables are double shielded. The two shields of the extension cables must not be
connected together: the inner shield of the extension cables is used as GROUND and must
be connected to GROUND*; only the outer shield must be connected to SHIELD* of the
connector.

PIN 4 (torque -) and PIN 1 (ground supply) are internally galvanically isolated; bridging
at the power source (not at the transducer) if required.
External EMC circuitry
A ceramic capacitor 100nF / 50V can be soldered between pins 4 - 5 on the evaluation
to avoid wirebound interference.
