NSTALLATION

The MX-4 can be fastened directly to a suitable surface or to a rigging clamp by

means of its adjustable mounting bracket. It can also be placed at an angle directly

on the stage or floor using the mounting bracket as a floor stand. Do not lay the

fixture flat on its pan/tilt arms: this can cause the fixture to overheat.

If using the GE Arcstream lamp, see “To orient the Arcstream lamp for maximum

life” on page 19.

Warning! Block access below the work area before proceeding.

Warning! Always use a secure means of secondary attachment.

To rig the MX-4

1 If using a rigging clamp (not included), verify that it is undamaged and can bear

at least 10 times the fixture’s weight. Bolt the clamp securely 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 hole in the center of the mounting

bracket.

2 If fastening the fixture directly, verify that the hardware (not included) and

mounting surface can bear at least 10 times the fixture’s weight. The four 6.2

mm holes and/or the 13 mm hole in the mounting bracket may be used.

3 Verify that the structure can support at least 10 times the weight of all installed

fixtures, clamps, cables, auxiliary equipment, etc.

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

5 Install a safety cable that can hold at least 10 times the weight of the fixture

through/over the support and through a hole in the pan/tilt arm.

6 Loosen the swivel locks and tilt the fixture to the desired angle. Turn the swivel

locks clockwise to tighten. If a swivel lock does not tighten fully, pull the handle

out, turn it counterclockwise, and retighten. Repeat as necessary.

7 Verify that the fixture is located at least 0.3 meters (12 in.) away from the

surface to be illuminated and at least 0.1 meters (4 in.) from any combustible

materials. Verify that the clearance around the fan and air vents is at least 0.1

meters (4 in.). Verify that there are no flammable materials nearby.
