Mounting the fixture on a truss
The fixture can be clamped to a truss or similar rigging structure in any orientation.
Use half-coupler type clamps (see illustration on right) that completely encircle the
truss chord or tubular support.
If installing the fixture outdoors, mount it so that the connections panel does not face
upwards. Ensure that cables arrive from below the fixture, creating 'drip loops' in
cables if necessary. Check that all rigging hardware is suitable for outdoor use.
To clamp the fixture to a truss:
1. Check that the rigging structure can support at least six times (or more if required
by local regulations) the weight of all fixtures and equipment to be installed on it.
2. Block access under the work area.
3. The fixture is supplied with two omega-type brackets. Bolt a half-coupler type rigging clamp that is in
perfect condition and approved for the weight that it will support securely to the each bracket. Use
M12, grade 8.8 steel minimum bolts with self-locking nuts.
4. Fasten the two omega brackets complete with rigging clamps to the base of the
fixture by locking each bracket's quarter-turn fasteners into two of the receptacles
(see B in illustration below) in the base of the fixture. The brackets must be spaced
evenly. Turn quarter-turn fasteners a full 90° to lock them as shown on right.

5. Note the position of the arrow marked FRONT (see A in illustration above). Working from a stable
platform, hang the fixture on the truss and fasten the two rigging clamps onto the truss with FRONT
pointing towards the main area to be illuminated.
6. Secure the fixture with a safety cable as directed below.
7. Make sure that there is no possibility of the head colliding with other fixtures or objects when it moves
through its full pan and tilt ranges.
Securing with a safety cable
1. Obtain a safety cable that is approved for the weight of the fixture.
2. Fasten the cable to one of the safety cable attachment points in the base of the fixture (see C in
illustration on previous page) by either looping it around or fastening a carabiner clip to the attachment
point. Do not use one of the fixture's carrying handles as the attachment point for the safety cable.
