RIGGING

This section briefly describes how to install the MAC 300 on a truss.

Location and orientation

The MAC 300 may be installed in any orientation. It shall be located at least 0.4 meters (16 inches) away from the sur-

face to be illuminated and any combustible materials. The lamp socket at the back of the head reaches temperatures up

to 150° C (302° F): the fixture should not be located in publicly trafficked areas.

Rigging hardware

The MAC 300 includes a clamp mounting bracket to which 1 or 2 rigging clamps (not included) can be bolted with

locking 12 mm (1/2 in.) hardware. The clamp bracket fastens to the base with 1/4-turn fasteners. For clamps available

from Martin, see the list of accessories on page 26.

To hang the fixture on a truss

WARNING!

Block access below the work area before proceeding.

Always fasten a safety cable to the reinforced attachment point in the base.

The 1/4-turn fasteners are locked only when turned fully clockwise.

Verify that the clamps are in good condition and can bear at least 10 times the weight of the fixture. Bolt

clamps to the bracket with a grade 8.8 (minimum) M12 bolt and lock nut, or as recommended by the

clamp manufacturer, through the 13 mm holes in the clamp mounting bracket.

Align the clamp mounting bracket with any 2 key slots on the base. Insert both locking pins into

the slots and turn both levers a full 1/4 turn clockwise to lock.

Verify that the structure can bear at least 10 times the weight of all installed fixtures, clamps,

cables, auxiliary equipment, etc.

Working from a stable platform, clamp the fixture to the structure.

Install a safety cable that can bear at least 10 times the weight of the fixture securely to the

structure and anchor the cable to the dedicated attachment point in the base. The attachment

point is designed to fit a carabiner clamp.
