When to use the lens safety clamp

The projection lens must be secured with a safety cable in any circumstance where the projector is mounted above people.

The lens safety clamp kit R9803511 is suitable for all “standard” FLD lenses except the UST 0.28 (R9802232) and UST 0.38 (R9801832) where the body geometry is different. For these UST lenses the lens safety cable kit R9801196 must be used.

Content of the lens safety clamp kit:

• lens safety clamp (consist in two brackets)
• lens safety cable (750 mm, Ø3 mm)
• 2 x screw M4x25
• 1 x shackle 7x70 mm

Required tools

How to install

1. Ensure that the lens safety clamp, safety cable, and all accessories are in good condition and free from damage.

2. Assemble the safety clamp around the lens body as follows:

   1. Position the clamp so that one joint is facing upward (reference 1) and the other downward (reference 2).
   2. Ensure that one loop end (reference 3) of the safety cable is secured within the clamp by the screw at the upper joint (reference 1).
   3. Position the clamp 15 mm away from the edge of the lens body.
   4. Tighten the screws to a torque of 2 Nm.

   

3. Attach the other end of the safety cable with the projector body, rigging frame, truss installation, or ceiling. Use the shackle to close loop.

   

   Note: The safety clamp is mounted as backup so that the drop distance is as small as possible. Keep the possible drop distance of the lens as short as possible!
