Mounting the fixture on a truss

The smartMAC can be clamped to a truss or similar rigging structure in any orientation. Clamp brackets can
be attached to the base of the fixture using quarter-turn quick connectors.
WARNING! Use two clamps to rig the fixture. Lock each clamp by turning both 1/4-turn fasteners
fully clockwise.
To clamp a smartMAC to a truss:
1. Check that the rigging structure
can bear at least 10 times the
weight of all fixtures and
equipment to be installed on it.
2. Obtain two rigging clamps and
check that they are undamaged
and can bear at least 10 times
the weight of the fixture. Bolt
each clamp securely to a clamp
bracket with a minimum grade
8.8 M12 bolt and lock nut.
3. See Figure 8. Align each of the
two clamp brackets with two
mounting points in the base.
Insert the quarter-turn fasteners
into the base and turn all levers a
full 90° clockwise to lock.
4. Block access under the work area. Working from a stable platform, hang the fixture on the truss with the
arrow on the base towards the area to be illuminated. Tighten the rigging clamps.
5. Secure the fixture against clamp or bracket failure with a safety wire that can bear at least 10 times the
weight of the fixture using the attachment point marked "SAFETY WIRE" in the base of the fixture. This
attachment point is designed to fit a carabiner clamp. Do not use carrying handles as safety attachment
points.
6. Check that the head will not collide with other fixtures or objects. Allow a minimum center-to-center
distance of 390 mm (15.4 ins.) minimum between smartMAC fixtures.
