Physical Installation; Mounting The Fixture On A Truss - Martin MAC 350 Entour User Manual

Physical installation

The MAC 350 Entour can be placed on a horizontal surface such as a stage or clamped to a truss in any
orientation. The quarter-turn clamp bracket mounting points in the base of the fixture allow clamp brackets
to be fastened parallel or perpendicular to the front of the fixture.
WARNING! Attach an approved safety cable to the attachment point labelled "SAFETY WIRE" in the
base of the fixture. Do not use the carrying handles for secondary attachment.
Check that all surfaces to be illuminated are minimum 500 mm (20 ins.) from the fixture, that
combustible materials (wood, fabric, paper, etc.) are minimum 200 mm (8 ins.) from the head, that
there is free airflow around the fixture (including the heatsinks in the yoke and base) and that there
are no flammable materials nearby.
Make sure that, wherever the product is installed, people are not able to look directly down the LED
beam from within a distance of 8.7 meters (28 ft. 7 ins.). At less than this distance, the LED emission
can cause eye injury or irritation. At distances of 8.7 meters (28 ft. 7 ins.) and above, light output is
harmless to the naked eye provided that the eye's natural aversion response is not overcome.
Make sure that it is impossible for the moving head to collide with another fixture or other object.

Mounting the fixture on a truss

The MAC 350 Entour 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 MAC 350 Entour 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 2. 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.
