2.3.2 Installing IRmax using a mounting bracket

a. IRmax can be supplied with a mounting bracket (S012130) rather than a spigot
gland so that it can be directly connected to field cables (see Diagram 5).

b. If the IRmax is to be mounted on a flat surface, mark and drill two holes using
the mounting bracket as a template. Loosely fix two parts of the bracket using
fixings suitable for the wall/surface.
c. Remove the weatherproof cap from the IRmax, and slide the body of the IRmax
through the bracket. It is recommended that the IRmax body is installed with the
cable entry facing downwards.
