REPLACEMENT OF HIGH VOLTAGE CABLES
WARNING... Electrical circuits inside the equipment use voltages that are capable of
causing serious injury or death from electrical shock. Use appropriate
precautions.
1. Verify the Workstation keyswitch is in the OFF position and the AC power plug is
disconnected from the wall socket.
WARNING... Apply only a small amount of silicon grease to High Voltage cable plugs at
the X-ray Tube end and then wipe them off to leave just a very thin layer of
grease.
2. Remove the X-ray Tube housing cover.
3. Remove the collimator cover, collimator and alignment bracket. Refer to Collimator
Replacement.
4. Use the spanner wrench (OEC part # 00-877674) to disconnect the anode and
cathode high voltage cables from the X-ray tube.
5. Unplug wiring connector J15 (stator motor power & temperature sensor).
6. Disconnect the ground wires from the X-ray tube.
7. Remove the High Voltage cable nuts and strain relief.
8. Remove the 4 bolts securing the X-ray tube assembly and remove it from the C-arm
weldment.
9. Release the C-arm brake and position the C-arm horizontal to floor.
10. Remove 2 Torx screws securing the camera cover.
11. Remove 4 Torx screws securing the Image Function PCB to the C-arm weldment if
necessary (Image Function PCB is in generator card rack on later models).
12. Remove 6 hex bolts securing the Image Intensifier. Lift the Image Intensifier and
place it on a chair while disconnecting 5 Torx screws securing the Image Intensifier
power supply. Refer to Image Intensifier/Power Supply Removal.
13. Remove 2 set screws securing the main trunk of the High Voltage Cable at the
cables injection point into the C-arm and then pull the cable out 4-5 inches.
14. Pull the High Voltage cables out until tension is felt and then push the cables back
in the cable injection point, towards the II end of the C-arm. Then reach in the II end
of the C-arm, grasp the loop of cable and pull the cables out the II end of the C-arm.
