ARF868 Radio Modems - Guide utilisateur / User guide version V2.2.2
•
IP67 option with the addition of a protective cover for the electrical connections by a system of
cable glands.
Mast/Post mounting
•
A universal accessory enabling the modem to be mounted on any type of base :
-
Various diameters of mast/post (flexible fins)
-
Flat plane (wall, board, etc)
•
The accessory should first be fixed to the intended base by means of screws or clips
FR
•
The modem can then be fixed to the accessory via the DIN-Rail lock.
In this position, the modem is at 90° in relation to the wall support; this enables the minimum dis-
tance between the aerial and metal bodies to be maintained.

90° wall mounting
•
An accessory enabling the modem to be mounted on a flat base (wall, board, etc)
•
The accessory should first be fixed to the base by means of 3 screws.
•
The modem can then be fixed to the accessory via the DIN-Rail lock.
•
In this position, the modem is parallel to the wall support. This type of mounting should not be
used on a flat metal base.
IP53 casing
The IP53 casing system comes in 3 parts:
•
The casing that fits under the bottom part to protect the connectors.
•
The clip-on bottom cover that allows the cables to pass.
•
The foam that fits between the cover and the bottom base of the casing and that, once it is
compressed, provides efficient sealing.
Fitting to the modem is done in the following order:
•
The electric cables fitted with their connectors are inserted into the casing through the bottom
and connected to the female bases on the modem (see electrical connection part).
•
The top part of the cover is then inserted onto the bottom plate of the modem holding the
female connectors which has previously been fitted with an O ring seal.
•
It is the U shaped modem shield that finally holds the IP53 casing once it is in place.
•
It then only remains to close the IP53 casing onto the bottom by the following operations:
•
The foam is positioned around the cables by means of the slots provided for the purpose; then
move it to its final position on the bottom of the casing.
•
Finally, clip the casing to compress the foam and eliminate the clearance around the wires of the
cables.
•
Internal dimensions : Height 42mm / Width 63mm / Thickness 25.2mm
•
External dimensions : Height 50mm / Width 67.5mm / Thickness 29.7mm
IP67 casing
•
This casing is constructed according to the same principle as the IP53 casing but it is fitted with
2 cable glands on the cable outlets to provide sealing against water splashing.
•
Its use is not compatible with cables already fitted with connectors as they cannot be inserted
through the cable glands.
•
Internal dimensions : Height 52.2mm / Width 63mm / Thickness 25.2mm
•
External dimensions : Height 83.5mm / Width 67.5mm / Thickness 29.7mm
Supply jack locking tool
•
Helps connection to the supply jack on standard versions when the profile of the modem bottom
plate does not allow easy access.
•
The tool is first inserted on the supply cable by means of its side opening and then slid along the
cable until it fits around the male jack for connection.
