NOTE: Twisted wires provide an effective shield that helps protect sensitive electronic components from electrical interference.

In order to prevent electrical interference from degrading the performance of the connected components, you must maintain the proper specification when making any repairs to the twisted wires shown

  • The wires must be twisted a minimum of 10 turns per 31 cm (12 in) as measured anywhere along the length of the wires.
  • The outside diameter of the twisted wires must not exceed 6.0 mm (0.25 in).
