Route Fiber-optic Cables

Fiber-optic cables are routed and connected at the factory in frame 8 and 9 drives and frame 8…10 bus supplies. Follow these procedures when installing frame 10 and larger drives and frame 11 and larger bus supplies.
  1. Locate and carefully uncoil the fiber-optic cables.
    IMPORTANT: Minimum inside bend radius for fiber-optic cable is 50 mm (2 in.). Any bends with a shorter inside radius can permanently damage the fiber-optic cable. Signal attenuation increases as inside bend radius is decreased.
  2. Sort the cables by length.
    The longest cables will be labeled with ‘Mn’ motor side power module numbers. Possible motor side power module numbers are M0…M9. Route the longest cables first.
  3. Working with one or two cables at a time, pull the cable down the power control channel until it reaches its corresponding power module.
    Use the cable guides provided to help organize the cables and keep them straight.
  4. Route cables for the right-to-left oriented cabinets through the grommet between the entry wire bays in back-to-back configurations.
  5. Route cables out of the power control channel and into the corresponding power module.
