11.3 Mounting – iRIS 350 / iRIS 350V
The iRIS can be mounted by installing suitable screws through the mounting pillars which are exposed when
the lid is opened. The recommended mounting screws are M4 machine screws or Twinfast® wood screws.
It is very important that the four screws retaining the lid are tightened firmly after installation to
maintain the IP66 rating of the enclosure.

The mounting holes are on 142mm (5.11in) width by 80mm (3.2in) height centres.
11.4 Antenna Connection
The iRIS 350 has an industry standard SMA connector which protrudes through the bottom edge of the
enclosure lid.
In areas of good signal strength, a small “stubby” or omni-directional type antenna will suffice. In areas of
more marginal coverage, the antenna should an external high gain type such as a Yagi, via appropriate low-
loss high frequency coaxial cable and male SMA connector.
