Physical installation

Read ‘Safety information’ on page 4 before installing the

fixture.

The fixture is designed for indoor use only and must be used in

a dry location with adequate ventilation. Ensure that none of the

fixture’s ventilation slots are blocked and ensure that the

product is fastened to a secure structure or surface.

Fastening the fixture to a flat surface

The fixture can be fastened to a hard, fixed, flat surface that is oriented at any

angle. Ensure that the surface and all fasteners used can support at least 10

times the weight of all fixtures and equipment they will support.

Fasten the fixture securely. Do not stand it on a surface or leave it where it

can be moved or fall over. If you install the fixture in a location where it may

cause injury or damage if it falls, secure it as directed below with a securely

anchored safety cable that will hold the fixture if the primary fastening method

fails.

Mounting the fixture on a truss

The fixture can be clamped to a truss or similar rigging

structure in any orientation. When installing the fixture

hanging vertically down, you can use an open-type clamp

such as a G-clamp. When installing in any other orientation,

you must use a half-coupler clamp (see illustration on right)

that completely encircles the truss chord.

To clamp the fixture to a truss:

1. Check that the rigging structure can support at least 10 times 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 to which rigging

clamps can be attached. Bolt a rigging clamp securely to each bracket.

The bolts used must be M12, grade 8.8 steel minimum, and fastened with

self-locking nuts.

4. Fasten the omega brackets to the base of the fixture

using the brackets’ quarter-turn fasteners. Turn quarter-

turn fasteners a full 90° to lock them (see illustration on

right).
