Mounting the fixture on a truss
The Atomic 3000 LED can be clamped to a truss or similar rigging structure in any orientation. When
mounting on a truss:
• Check that the rigging structure can support at least 10 times the weight of all fixtures and equipment to
be installed on it.
• Check that all rigging hardware is undamaged and rated for the weight it will secure.
• Block access under the work area.
• Work from a stable platform.
• Secure the fixture against rigging hardware failure with an approved safety cable.
Depending on the orientation of the fixture, you can use one of the following methods to mount the fixture on
a truss.
Truss-mount installation in any orientation
Warning! Do not use G-clamps, quick-trigger clamps or any other type of
clamp that does not completely encircle the supporting
structure when fastened, do not use an omega clamp and do
not use quarter-turn fasteners to attach rigging hardware
unless the fixture is hanging vertically in ‘free hanging mode’
as described below.
To suspend the fixture from a rigging structure such as a truss in any
orientation:
1. Fasten a half-coupler rigging clamp (see “Accessories” on
page 38) that completely encircles the truss chord directly to the
fixtures’s mounting bracket by means of an M12 grade 8.8 bolt
passed through the hole in the mounting bracket and secured
with an unworn self-locking nut. Do not use an omega bracket.
2. Block access under the work area. Working from a stable
platform, hang the fixture on the truss and fasten the half-coupler clamp around the truss chord.
3. If the fixture may fall and cause injury or damage if the primary attachment fails, attach an approved
safety cable to a secure anchoring point and to one of the safety cable attachment points on the fixture
(see Figure 1 on page 7).
4. If necessary, adjust the orientation of the fixture by loosening the tilt adjustment wheels (see Figure 1 on
page 7), adjusting the aim of the fixture and retightening the tilt adjustment wheels. Apply firm pressure
by hand only – do not use tools to tighten the tilt adjustment wheels.
Truss-mount installation hanging vertically in ‘free hanging mode’
It is possible to install the Atomic 3000 LED hanging vertically
downwards from a truss and then set it to the required tilt
using the tilt adjustment wheels in the mounting bracket. To
suspend the fixture from a rigging structure such as a truss
with the fixture hanging vertically in ‘free hanging mode’ only :
1. See Figure 4. Bolt any safe type of rigging clamp (see
“Accessories” on page 38) to a Martin omega bracket, P/N
91602001 with an M12 grade 8.8 bolt passed through the
hole in the omega bracket and secured with an unworn
self-locking nut.
