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 sige 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, use basically a
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.
