2.2.2 Mounting the instrument
Ideally, the UFB enclosure should be fixed to a wall using three screws – see Figure 2.2.
1. Remove the UFB terminal cover.
2. Fix a screw into the wall at the required point to align with the mounting keyhole on the back of the enclosure.
3. Attach the enclosure to the wall using the keyhole screw mounting.
4. Align the enclosure then mark out the positions for the two remaining screw fixings through the slots near the
bottom corners of the enclosure. Then remove the enclosure, and drill (and plug) the two fixing points.
5. Clear the site of any dust/debris, then mount the enclosure on the wall.
