When to use the lens safety cable

The lens safety cable must be used in any circumstance where the projector is mounted above people. Do this to secure the mounted lens in the lens holder.

Content of the lens safety cable kit (R9801196)

• Safety Cable (750 mm, Ø3 mm)
• Cable clamp M4 (U-bolt)
• Shackle 7x70 mm
• 20 x Cable clip (16x16 mm, Ø4 mm)^[5]

How to install the lens safety cable

1. Ensure that the safety cable and its accessories are in good condition (not damaged)

2. Paste four cable clips on the lens body between motor block and lens flange as illustrated (reference 1). Orient the open side of the clips towards the front of the lens.

   

   

3. Snap the first loop end of the safety cable into one of the following clips and let the loop end point downwards.

   1. Configuration A: Use the upper clip on the side of the cable bundle (reference 2, Image 5–6).
   2. Configuration B: Use the upper clip on the non-wired side (reference 2, Image 5–7).

4. Slide the rest of the cable around the lens counterclockwise. Click the cable into every clip it passes in this loop.

   

   Note: Make sure the cable passes between the lens and the cable bundle.

5. Slide the cable through the loop end at the beginning of the cable to create a lasso..

   

6. Pull the lasso tight around the lens body and install the U-bolt on the lens holder, with the open ends oriented outwards (reference 3). Make sure that both a part of the loop end and the outgoing part of the safety cable are placed in the enclosure.

   

   

7. Close the U-bolt and tighten it.

   

   Note: Make sure the safety cable is tightened around the lens before tightening the U-bolt nuts.
8. Place the shackle through the free loop end of the safety cable.

9. Connect the shackle on the truss or rigging frame.

   

   Caution: The safety cable 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!

How to mount the cable to a short barrel lens

1. Paste two cable clips on both sides of the lens as illustrated (reference 1). Orient the open side of the clips towards the outside of the lens.

   

   

2. Paste two extra cable clips on the motor block of the lens. Orient the open side to the outside of the lens.

   

3. Carefully slide the safety cable through the cable clips. Make sure the cable is placed between the motor block and the cover plate.
4. Slide the cable through the loop end at the beginning of the cable.
5. Mount a U-bolt on the cable, with the open ends oriented outwards (reference 3, Image 5–13). Make sure that both a part of the loop end and the outgoing part of the safety cable are placed in the enclosure.

6. Close the U-bolt and tighten it.

   

   Note: Make sure the safety cable is tightened around the lens before tightening the U-bolt nuts.

   The result should look similar to the following example.

   

7. Lead the cable end with the shackle around rigging frame bar or truss bar

8. Snap the shackle to the straight part of the cable.

   Secure the shackle by screwing the safety ring of the shackle over the open end.
