Physical Installation; Placing The Fixture On A Flat Surface; Mounting The Fixture On A Truss - Martin MAC 301 Wash User Manual

Physical installation

The MAC 301 Wash can be placed on a horizontal surface such as a stage or clamped to a truss in any
orientation using the quarter-turn clamp brackets supplied with the fixture.
Warning! Attach an approved safety cable to the attachment point on the connections panel (see
"Fixture overview" on page 6).
Check that all surfaces to be illuminated are minimum 250 mm (10 ins.) from the fixture, that
combustible materials (wood, fabric, paper, etc.) are minimum 100 mm (4 ins.) from the head, that
there is free airflow around the fixture and that there are no flammable materials nearby.
Make sure that it is impossible for the moving head to collide with another fixture or other object.

Placing the fixture on a flat surface

The MAC 301 Wash can be placed on a stage or other level, flat surface. Check that the surface can
support at least 10 times the weight of all fixtures and equipment to be installed on it.
Warning! The supporting surface must be hard and flat or air vents in the base may be blocked,
which will cause overheating. Secure the fixture against falling. Attach a securely anchored safety
cable to the safety cable attachment point (see "Fixture overview" on page 6) if the fixture is to be
placed above ground level in any location where it may fall and cause injury or damage.

Mounting the fixture on a truss

The MAC 301 Wash 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 bracket by turning both 1/4-turn
fasteners fully clockwise.
To clamp a MAC 301 Wash to a truss:
1. Check that the rigging structure can support 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 the clamps securely
to the supplied clamp brackets 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.
5. Secure the fixture against clamp or bracket failure with a secondary attachment such as a safety cable
that can bear at least 10 times the weight of the fixture using the attachment point on the connections
panel (see "Fixture overview" on page 6). This attachment point is designed to accept a carabiner
clamp. Do not use any other part of the fixture as a safety cable attachment point.
6. Check that the head will not collide with other fixtures or objects.
