Procedure

  1. Make sure the table lock safety bar is lowered and the weight of the table is resting on it.
    Figure 1. Lock safety bar down
  2. Remove the extra cable ties installed at the upper cable track end nearest to the P-port connectors for shipping. There should only be one cable tie around the entire cable bundle at the end of the cable track.
    Figure 2. Upper cable track cradle end cable tie
  3. Route the ODU connectors and cables, and the lower cable track from the tabletop to the table base through the left-hand tabletop opening.
  4. Route the Electro-CardioGram (ECG) cable from its exit at the left-hand upper cable track through the left-hand tabletop opening, and then along the left-hand Touch-and-Go (TnG) cable securing the cables to the two cable tie mounts at the bore end of the table.

  5. Remove the cable ties securing the cables to the left-hand upper cable track strain relief bracket.
  6. Install the two screws securing the left-hand upper cable track strain relief bracket to the top of the tabletop.

    2Strain relief bracket
  7. Install cable ties securing the cables to the left-hand upper cable track strain relief bracket in the same locations and configuration as they were removed.
    Important: The cable ties must be reinstalled immediately after the strain relief bracket is secured to the tabletop. The cable ties are critical to cable track function.
  8. Install the two screws securing the left-hand cable protection plate to the tabletop.

  16. Install cable tie(s) securing the cables to the left-hand inner cable bracket.
    Important: Make sure the cables and the cable tie(s) are within the inner radius of the cable bracket. Cable(s) or cable tie(s) outside of the inner radius may interfere with table operation or damage the cable(s).
  17. Route the following cables in the right-hand lower cable track, exiting the track at the top of the track and routing around the bellows cover bracket as shown.
    • Motor power
    • Motor signal
    • String encoder
    Note: Open the right-hand lower cable track to route the cables if it is not already open.

  19. Route the PAC fiber optic cable through the track to exit the back of the track where the PAC 1-wire and PAC power cables exit.
    Figure 12. PAC cable track exit
  20. Close the right-hand lower cable track.
  21. Route the two motor cables and the string encoder cable with the dummy load cable along the side of the table, installing cable ties as shown below.
    Figure 13. Motor and dummy load cable tie locations
  22. Connect the motor power, motor signal, and string encoder connectors.
  23. Install cable ties securing the motor and signal encoder connectors to the cable tie mounts on the bottom of the tabletop.

  37. Install cable tie(s) securing the cables to the left-hand outer cable bracket.
    Important: Make sure the cables and the cable tie(s) are within the inner radius of the cable bracket. Cable(s) or cable tie(s) outside of the inner radius may interfere with table operation or damage the cable(s).
  38. Route the up-limit switch cable from the PE ODU connector to the left-hand support bar and secure the cable to only one loop of the cable tie mount on the inside of the bar.
    Important: Make sure there is at least 25 mm (1 inch) of slack behind the cable tie mount with the electrical sled all the way forward.
    Important: Make sure the cable is tightly tied to only one loop of the cable tie mount.

    Figure 30. Home switch and electro-magnetic clutch cable tie mounts
  47. Push the cables in the left-hand lower cable track such that the cable slack is at the top exit of the track.
  48. While holding the slack at the top exit of the track, adjust the position of the slide plate until the edge of the slide plate is aligned with the edge of the support bracket. Make sure the distance between the spring mounting locations shown is 90 ± 5 mm from outer end to outer end.
    Figure 31. Slide plate alignment
    1Slide plate edge
    2Support bracket edge
    3Spring mounting distance
  49. When the distance is within tolerance, install four cable ties securing the cables to the end of the cable track plate. Split the cable into two approximately equal bundles and install two of the cable ties on each half bundle.
    Figure 32. Half-bundle cable tie locations
  50. Install the spring onto its support.
  51. Install two cable ties securing the cables to the top exit end of the cable track, one cable tie per half bundle.
  52. Route the slack of the cables exiting the top of the lower cable track forward and install four cable ties securing the cables to the cross-beam cable bracket. Install one cable tie on each half bundle at each end of the bracket.
    Important: Make sure the cables are within the outer edges of the bracket. Cable(s) or cable tie(s) outside of the edges of the bracket may interfere with table operation or damage the cable(s).
    Figure 33. Bracket cable tie locations
  53. Install cable ties securing the cables to the multiple cable tie bracket. Secure one white cable per cable tie and two smaller cables per cable tie.
    Note: For ease of installation:
    1. Loosely install the cable tie around the cable(s).
    2. Slide the cable tie onto the bracket hook.
    3. Hold the square portion of the cable tie while pulling the cable tie tight.
      Important: Pulling the cable tie tight without holding it may cause the bracket hook to bend.
