MAC 401 Dual™ user manual
Physical installation
The MAC 401 Dual™ 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 and a half-coupler (not supplied).
Warning! Attach an approved safety cable to the attachment point on the connections panel (see
Figure 2).
Check that all surfaces to be illuminated are minimum 200 mm (8 in.) from the fixture, that
combustible materials (wood, fabric, paper, etc.) are minimum 200 mm (8 in.) 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.
Ensure that wherever the product is installed that people are not able to look directly down the LED
beam zone from within a distance of 1 meter (3 feet 4 inches). At less than this distance, the LED
emission can cause eye injury or irritation. At distances of 1 meter (3 feet 4 inches) and above, light
output is harmless to the naked eye provided that the eye’s natural aversion response is not
overcome.
Placing the fixture on a flat surface
The MAC 401 Dual™ 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 Figure 2) 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 401 Dual™ 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 401 Dual™ 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. 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 in the base of the fixture
(arrowed in Figure 2). 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.
