Clamping the fixture on a truss
1. Check that all rigging hardware is undamaged and can bear at least 10 times the weight of the fixture.
Check that the structure can bear at least 10 times the weight of all installed fixtures, clamps, cables,
auxiliary equipment, etc.
2. Bolt each rigging clamp securely to an omega bracket with an M12 bolt (minimum grade 8.8) and
self-locking nut.

3. See Figure 3 on page 7. Align the first
clamp and bracket with 2 mounting points
in the base, and engage both the clamp
bracket's quarter-turn fasteners in
corresponding sockets in the base. See
Figure 4. Turn the levers on the
quarter-turn fasteners a full 90° clockwise
to lock. Repeat for the second clamp.
4. Block access under the work area. See
Figure 5. Note the position of the arrow
marked FRONT on the base of the fixture.
Working from a stable platform, hang the
fixture on the truss with the arrow marked
FRONT facing towards the area to be
illuminated. Tighten the rigging clamps.
5. See Figure 6. Install a safety cable that is
approved as a safety attachment for the
weight of the fixture by looping it through
the safety attachment point (arrowed) in
the bottom of the base and around a
secure anchoring point so that the safety
cable will catch the fixture if a primary
attachment fails.
6. Check that the tilt lock is released. Check
that there are no combustible materials
within 0.2 m (8 in.) or surfaces to be
illuminated within 2.0 m (6.6 ft.) of the
fixture, and that there are no flammable
materials nearby.
7. Check that there is no possibility of heads
or yokes colliding with other fixtures.
8. Check that other lighting fixtures cannot project intense light at the MAC Quantum Profile, as intense
illumination can damage the MAC Quantum Profile's display.
