Removing the Patient Handling Power Supply (PHPS) 2

Procedure

  1. Open the penetration cabinet door far enough to provide clearance and access to the inside of the cabinet.

  2. Disconnect the cables from the front of the PHPS 2.
  3. Disconnect the fiber optic cable from the front of the fiber optic interface.
  4. Loosen four captive fasteners.

  6. Disconnect the cables from the rear of the PHPS 2.
  7. Disconnect the fiber optic cable from the rear of the fiber optic interface.
    Note: Make sure the cables do not fall to the back, where it is difficult to retrieve them.
