Remove Frame 8…15 LCL Filter Module

Follow this procedure to remove the LCL filter module from a frame 8…15 enclosure.
If power modules need to be removed, follow these steps to remove them.
  1. Review the product advisories in the Before You Begin section.
  2. Open the enclosure door.
  3. If present, remove the protective guards from the enclosure.
  4. Loosen the screw that secures the connections cover to the front of any adjoining power module.
  5. Use the screw to lift the connections cover up and off the power module chassis.

    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.
  6. Disconnect the PDI and CTL fiber-optic cables, if present, from the power layer interface circuit board.

  7. Without bending the cable to a radius less than 50 mm (2 in.), carefully remove the disconnected fiber-optic cables from the power module chassis.
  8. Disconnect any P1 through P4 cables that are plugged into the I/O panel in the power modules.
  9. Carefully remove the disconnected cables from the power module chassis.

  13. Leave the two M10 x 20 mm screws that secure the LCL filter module chassis to the floor mounting bracket while preparing the
    PowerFlex®
     750-Series service cart.
  14. Secure the service cart to the floor mounting bracket in the enclosure. See PowerFlex 750-Series Service Cart Instructions, publication 750-IN105, for information on using the service cart.
  15. To release the LCL filter module, remove the two remaining M10 screws that secure the module to the cabinet floor.
  16. To remove the LCL filter module from the enclosure, use the service cart, 20-750-MCART1.

    ATTENTION:
    Risk of injury, death, or equipment damage exists.
    IGBT power and LCL filter modules have a high center of gravity and may pose a tip-over hazard. To guard against death, serious personal injury, or equipment damage, do not subject the module to high rates of acceleration or deceleration while transporting. Do not push or pull above the points that are indicated on the module.
