6.1.2 Installing the camera
This section describes how to install the camera
inside the housing.
Open the housing following the instructions given
above (
Fig. 01, page 5 ).
Attach the camera to the internal slide with the 1/4”W
screw using the insulating bush. If necessary use the
spacers supplied and the appropriate 1/4”W screws
so as to position the camera and lens correctly.

Make the correct electrical connections for the
camera and lens, passing the cables through the
cable glands. Make sure the latter are firmly locked
in place.
Close the housing by proceeding in the reverse order
to that described above (
Fig. 01, page 5
). Make sure the
sealing ring on the rear flange is correctly inserted in
its seating so as not to damage it.
Attach the housing to the bracket if this has not been
assembled already.
