Cable shield
It is recommended to use a shielded cable for stable measurement.
With Terminal block: The cable shield can be connected either to terminal 3 or on the other
side to earth. Do not connect both sides of the shield to earth. Note: terminal 3 is internally
connected to the external equipotential bonding terminal on the enclosure.
With M12 plug: With use of common M12 cables, the cable shield is connected with the M12
cap nut. Since the M12 thread on LCS100 is made of plastics, the cable shield on the M12 cap
nut is not connected with LCS100 and must be connected on the other side to ground.
