Installing / rigging the S-4 Fresnel
The S-4 Fresnel may be installed in any orientation by using the supplied omega bracket.
Always use the omega bracket to rig the xture and lock the bracket with the 1/4-turn fasteners.
Please note:
The 1/4-turn fasteners are only locked when turned fully clockwise.
Rigging process
Start the rigging process by blocking the working area below the xture. Make sure the work is performed from a stable platform.
1. Check that the clamp is undamaged and can bear
at least 10 times the weight of the xture. Check
that the structure can bear at least 10 times the
weight of all installed xtures, lamps, cables, etc.
2. Bolt the clamp securely to the omega bracket
with a M12/ ½ bolt (min. grade 8.8) and a lock
nut.
3. Align the omega bracket with the two 1/4 turns in
the base. Insert the fasteners into the base and
turn both levers a full 1/4-turn clock wise to lock.
4. From a stable platform, hang the xture on a
truss or other structure. Tighten the clamp.
5. Install a safety wire that can bear at least 10
times the weight of the xture.
6. Verify that there are no combustible materials, cables, or surfaces within a distance of 0.3m (12 in.) from the xture.
7. Check that there is no risk of colliding between the head / yoke and other xtures or structures.

Unpacking
Unpack the S-4 Fresnel and inspect it to ensure that it has not been damaged during transport.
The S-4 Fresnel is shipped with:
• One Neutrik TRUE1 power input connector, 2 m (78 in).
• One Omega bracket with 1/4-turn fasteners.
Location / application
The S-4 Fresnel is IP65-rated and designed for use in outdoor events. This means that it is protected from:
• Dust, to the degree that dust cannot enter the device in sufcient quantities to interfere with its operation.
• Lower pressure jets of water from any direction.
Please be advised when installing the motorized barndoors front lens in the S-4 Fresnel that, while the xture is fully IP65-rated, the
motorized barndoors module is IP20-rated. Therefore, the motorized barndoors are not protected from water and dust.
When selecting a location for the device, ensure that:
• It is situated away from public thoroughfares and protected from contact with people.
• It is not immersed in water or exposed to high-pressure water jets.
• It has adequate ventilation.
When using the xture for outdoor events, ensure that:
• For wireless DMX or standalone operation, the protective caps are securely mounted in any unused DMX connectors.
• For cabled DMX operation, the DMX out of the last xture is terminated with a 120 Ohm resistor between pin 2 and 3
(according to the RS485 standard), and the DMX out is properly sealed (according to the IP65 requirements).
A maximum of 32 xtures can be connected to the same DMX link.
Transportation
Always use the supplied packaging or a suitable ight case for transportation and storage of the device.
Never carry your S-4 Fresnel by connected cables, wires, barndoors, or motorized barndoors (when installed). Doing so may cause
severe damage to the xture. Always use the handles to carry the xture.
