Connect the product in accordance with the specification of the external device.
Notes on the Shield Connection
Ground the shield to the frame ground (FG) of the external device.
Use an unshielded cable if there is no terminal or/and place for grounding.
Do not ground to Power GND.
Shield should not be used as the signal ground (SG).
CAUTION
Tightening torque of the supplied connector is described below.
DEGSON : 0.19 N·m, PHOENIX CONTACT, PTR MESSTECHNIK : 0.25 N·m
Strip off approximately 7mm (plus or minus 0.5mm) of the covered part of a cable to connect
with the connector.
If the shielded cables are incorrectly wire-connected to the ground, the shield might become
an antenna picking up noises or become a source of noise.
If you find the problems, remove the grounding of the shield.
About a caution mark on the product: Please use copper wires that withstand the temperature
