Physical Installation; Fastening The Fixture To A Flat Surface; Mounting The Fixture On A Truss - Martin MAC Aura User Manual

Physical installation

Warning! The MAC Aura must be either fastened to a flat surface such as a stage or wall, or clamped to a
truss or similar structure in any orientation using a rigging clamp. Do not apply power to the MAC Aura if it is
standing freely or the fixture can be moved.
Warning! Attach an approved safety cable to one of the safety cable attachment points on the base
(see "Fixture overview" on page 6).
Check that all surfaces to be illuminated are minimum 200 mm (7.9 ins.) from the fixture, that
combustible materials (wood, fabric, paper, etc.) are minimum 100 mm (3.9 in.) from the fixture, 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.
Allow a minimum center-to-center distance of 300 mm (12 ins.) between MAC Aura fixtures.

Fastening the fixture to a flat surface

The MAC Aura can be fastened to a stage or other 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. Fasten the fixture securely. Do not stand it on a surface or leave it
where it can be moved or can fall over. Attach a securely anchored safety cable to the safety cable
attachment point (see "Fixture overview" on page 6) if the fixture is to be installed in any location
where it may fall and cause injury or damage.

Mounting the fixture on a truss

The MAC Aura can be clamped to a truss or similar rigging structure in any orientation.
Warning! Use a rigging clamp with an M12 bolt if suspending the fixture from its base. The clamp
must be screwed into the central threaded hole in the fixture base. The M12 bolt must protrude
20 - 30 mm (0.8 - 1.2 ins.) into the fixture base.
An M12 bolt that is suitable for many types of rigging clamp is supplied with the MAC Aura, but you
must pass the bolt through the clamp and check that the distance the bolt will protrude into the
fixture base is within the 20 - 30 mm limits before using it. If the bolt is not within these limits, you
must find an alternative bolt that is.
To clamp a MAC Aura 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 a rigging clamp
such as the G-clamp
(P/N 91602003),
Half-coupler clamp
(P/N 91602005) or
Quick trigger clamp
(P/N 91602007)
available as
accessories from
Martin. An omega bracket is not required.
3. Check that the rigging clamp is undamaged and can bear at least 10 times the weight of the fixture.
Fasten the clamp to the fixture with a minimum grade 8.8 steel M12 bolt in the threaded hole in the
