or the fixture’s cooling airflow will be affected, leading to excessively high fixture temperature and
reduced light output.
Do not stand the fixture freely on a surface or leave it where it can be moved or fall over. Ensure
that the installation surface or structure and all fasteners used can safely bear at least 10 times the
weight of all the fixtures and equipment they will support.
Installing on a rigging truss
It is possible to install the fixture temporarily on a rigging truss or similar support. If you do this,
fasten two approved rigging clamps to the mounting yoke with two M12 bolts minimum grade 8.8
strength fastened through holes
B in the mounting yoke base (see illustration on next page) and
suspend the fixture using the two clamps.
Do not suspend the fixture from only one clamp: use two approved rigging clamps. Install the
fixture hanging vertically downwards only. Secure the fixture with a safety cable as described in
‘Safety cable attachment’ on page 14. Check that the truss and all fasteners used can support 10
times the weight of all the fixtures and equipment that they will support.
Anchoring to a surface or structure
The fixture’s mounting yoke base must be securely anchored to a flat surface on a wall, pedestal,
structural beam or other suitable support. The yoke allows the fixture to be manually panned and
tilted for beam aiming adjustment.
To anchor the fixture to a surface:
1. See Mounting yoke base illustration on next page. Fasten a 12 mm (1/2 inch) shaft diameter
bolt to the surface through the center hole A in the mounting yoke.
2. Fasten two bolts with 8 mm (5/16 inch) shaft diameter to the surface with one bolt passing
through each of the curved slots C to anchor the fixture. This will give approximately 90° of
pan adjustment.
3. Adjust the fixture’s pan angle (side-to-side beam aiming) as described later in this chapter.
Adjusting pan is best carried out with power applied to the fixture so that the projection is
visible. Once pan is correct, fasten two 12 mm (1/2 inch) shaft diameter bolts to the surface
with one bolt passing through each of the holes
B . Once bolts have been installed in holes B ,
pan adjustment is no longer possible.
