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 shielded cable.
(2) The size of converter terminal screw threads is M4. Each cable should be terminated
corresponding crimp-on terminals.
The ground wiring of the detector should be connected to the ground terminal of the
detector case. The ground wiring of the converter should be connected to either the
ground terminal of the converter case or the protective ground terminal in the equip-
ment. The grounding terminals of the detector and the converter are of size M4. Proceed
as follows:
(1) Keep ground resistance to 100 or less (JIS Class 3 ground).
(2) When the ambient temperature of the wiring installation is 80 to 150 C for the wiring
of the detector, use wiring material with sufficient heat resistance.
(3) When connecting the ground wiring to the ground terminal of the converter case, be
sure that the lock washer is in contact with the case surface (see Figure 5.10.).
(4) Ensure that the jumper plate is connected between the G terminal and the protective
ground terminal of the converter.
