Notice when closing the cover of the detector
NOTE
• Before opening the detector cover, loosen the lock screw. If the screw is not loosened first,
the screw will damage the cover, and the terminal box will require replacement.
When opening and closing the cover, remove any sand particles or dust to avoid gouging the
thread.
• After screwing the cover in the detector body, secure it with the lock screw.

5.3.3 Connection to Converter
To connect the wiring to the converter, proceed as follows:
(1) M4 screws are used for the terminals of the converter. Each cable should be terminated in
the corresponding size crimp-on terminals.
(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
insulated PVC sheathed cable.
CAUTION
The above is to prevent moisture or corrosive gas from entering the converter.
Where the ambient environment of the detector and the converter is well-maintained, it is
permissible to connect the wiring from the detector directly to the converter with protection by
conduits.
WARNING
This wiring is to carry power for the heater. Be careful to wire the correct terminals, and be
careful not to ground or short circuit terminals when wiring, as otherwise the instrument may be
damaged.
