5.4.1 Cable Specications
For this wiring, use a 2-core or a 4-core shielded cable.
5.4.2 Wiring Procedure
(1) M4 screws are used for the terminals of the converter. Each wire in the cable should be
terminated corresponding to crimp-on terminals. Ensure that the cable shield is connected
to the FG terminal of the converter.
(2) Be sure to connect “+” and “-” polarities correctly.
5.5 Power and Grounding Wiring
This wiring supplies power to the converter and grounds the converter/detector.

5.5.1 Power Wiring
Connect the power wiring to the L and N terminals of the converter. Proceed as follows:
(1) Use a 2-core or a 3-core cable.
(2) The size of converter terminal screw threads is M4. Each cable should be terminated
corresponding to crimp-on terminals.
