5. Wiring
5.2.3 Connection to the Converter
To connect the wiring to the converter, proceed as follows:
(1) M4 screws are used for the terminals of the converter. Each wire in the cable should
be terminated in the corresponding size crimp-on terminal.
(2) When a rubber insulated glass braided wire is used for wiring to the detector, use a
terminal box. For wiring between the terminal box and the converter, basically use
cable, e.g. PVC sheathed PVC insulated cable, rather than individual wires.
Note
The above is to prevent moisture or corrosive gas from entering the converter and to
ground the detector without fail.
