• Fasten the fixture securely to a fixed surface or structure when in use. The fixture is not portable when
installed.
• When clamping the fixture to a truss or other supporting structure at any other angle than with the yoke
hanging vertically downwards, use a half-coupler clamp fastened to the truss chord or similar bar. Do not
use G-clamps, quick-trigger clamps or any other type of clamp that does not completely encircle the
supporting structure when fastened.
• When suspending the fixture, ensure that the supporting structure and all hardware used can hold at least
10 times the weight of all the devices they support.
• If suspending from a rigging structure, fasten the fixture to a rigging clamp with an M12 bolt screwed into
the threaded hole in the center of the base of the fixture. The bolt must protrude at least 20 - 30 mm
(0.8 - 1.2 ins.) into the fixture. If the fixture is suspended by any other method, an M12 bolt must be
tightened into this hole so that it protrudes at least 20 - 30 mm (0.8 - 1.2 ins.) into the fixture.
• If the fixture is installed in a location where it may cause injury or damage if it falls, install as described in
this manual a secondary attachment such as a safety cable that is approved by an official body such as
TÜV as a safety attachment for the weight that it secures. The safety cable must comply with EN
60598-2-17 Section 17.6.6 and be capable of bearing a static suspended load that is ten times the weight
of the fixture and all installed accessories.
• Check that all external covers and rigging hardware are securely fastened.
• Block access below the work area and work from a stable platform whenever installing, servicing or
moving the fixture.
• Allow enough clearance around the head to ensure that it cannot collide with an object or another fixture
when it moves.
