3.1 How to mount the 505U
The 505U module is housed in an IP66 weatherproof aluminium enclosure. To mount the 505U,
remove the four screws in the top plate, and carefully remove the cover. The two mounting holes
should now be visible.
It is important to effectively earth the unit to help prevent radio noise and static electricity damage.
The preferred method is to earth the module using the mounting screws to connect to an earthed
surface. If this is not possible, use an earth lug in the mounting screw connection and secure the
other end of the wire to a good earth.
3.2 Antenna Installation
The 505U module will operate reliably over large distances. The distance that may be reliably
achieved will vary with each application - depending on the type and location of antennas, the
degree of radio interference, and obstructions (such as hills or trees) to the radio path. Where it is
