Rigging - Martin MAC 2000 Wash XB User Manual

Rigging

The MAC 2000 Wash XB can be placed on stage or clamped to a truss in any orientation. The Fast-Lock
system enables quick and easy fastening of the clamp brackets in 4 positions as shown Figure 4.

Warning! Always use 2 clamps to rig the fixture. Lock each clamp with both 1/4-turn fasteners. The
fasteners are locked only when turned fully clockwise.
Warning! Attach an approved safety cable to the attachment hole in the base. Never use the carrying
handles for secondary attachment.
Warning! When a fresnel lens (medium beam angle) or a micro-fresnel lens (very narrow beam
angle) is installed, the head must be positioned so that the lens does not face the sun directly at any
time during daylight hours. These two lenses can focus the sun's rays inside the fixture, causing
internal damage and creating a possible fire risk.
Clamping the fixture to a truss
1 Verify that the rigging clamps (not included) are undamaged and can bear at least 10 times the weight of the
fixture. Verify that the structure can bear at least 10 times the weight of all installed fixtures, clamps, cables,
auxiliary equipment, etc.
2 Bolt each clamp securely to a clamp bracket with an M12 bolt (grade 8.8 or better) and lock nut.
3 Align a clamp with 2 mounting points in the base. Insert the fasteners into the base and turn both levers a
full 1/4-turn clockwise to lock. Install the second clamp.
4 If the truss can be lowered, fixtures can be clamped on directly from the double flight case. If the fixture
must be lifted, block access under the work area. Working safely from a stable platform, hang the fixture on
the truss with the arrow towards the area to be illuminated. Tighten the rigging clamps.
5 Install a safety wire that can bear at least 10 times the weight of the fixture. The attachment point is
designed to fit a caribiner clamp.
6 Verify that the pan and tilt locks are released. Verify that there are no combustible materials within 1 m (39
in.) of the fixture, that there are no flammable materials nearby, and that surfaces to be illuminated are at
least 3 m (10 ft.) away.
