Physical installation
Warning! The MAC Quantum Profile has a powerful pan motor. The torque reaction when the head is
panned suddenly can cause the base to move if the fixture is standing unsecured on a surface. Do
not apply power to the MAC Quantum Profile unless the base is securely fastened to a surface or to
rigging hardware.
Warning! Use 2 clamps to rig the fixture. Do not hang the fixture from only one clamp. Lock each
clamp with both 1/4-turn fasteners. Fasteners are locked only when turned a full 90° clockwise.
Warning! When suspending the fixture above ground level, secure it against failure of a primary
attachment using a safety cable that is approved as a safety attachment for the weight of the fixture
together with mounting hardware, accessories, etc. Do not use the carrying handles for secondary
attachment.
Warning! When clamping the fixture to a truss or other structure at any other angle than with the
yoke hanging vertically downwards, use two clamps of half-coupler type. Do not use any type of
clamp that does not completely encircle the structure when fastened.
Warning! Position or shade the head so that the front lens will not be exposed to sunlight or any
other strong light source from any angle – even for a few seconds. See Figure 2. The MAC Quantum
Profile’s lens can focus the sun's rays, creating a potential fire hazard and causing damage.
Important! Do not point strong light output from other fixtures at the MAC Quantum Profile, as
intense illumination can damage the display.
See Figure 2. Lenses can focus sunlight and strong light, presenting a risk of fire and damage to the fixture.
Shield or shade the head if necessary.
The MAC Quantum Profile can
be fastened to a surface such as
a stage or clamped to a truss in
any orientation. Clamps must be
half-coupler type (see Figure 4)
or equivalent type that fully
encircles the truss unless the
fixture is installed with the yoke
hanging vertically downwards,
in which case other clamp types
that are approved for the
supported weight may be used.
The mounting points in the base
allow omega brackets and
rigging clamps to be fastened
as shown in Figure 3.
