This section briefly describes how to install the MAC 300 on a truss.
L o c a t i o n a n d o r i e n t a t i o n
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.
R i g g i n g h a r d w a r e
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 h a n g t h e f i x t u r e o n a t r u s s
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
1.
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.
2. 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.
3. Verify that the structure can bear at least 10 times the weight of all installed fixtures, clamps,
cables, auxiliary equipment, etc.
4. Working from a stable platform, clamp the fixture to the structure.
5. 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.
