OEC 9800 Periodic Maintenance Procedure
6
WARNING
:
After taking X-rays, the high voltage cables can retain a lethal charge, even if you power down
the system. Even though the contacts are recessed, high voltages can arc several inches from
their terminals if the cables are removed from the connector wells. Use caution when
disconnecting high voltage cables even when the power is turned
off
. If you remove these
connections, immediately discharge their contacts against the high voltage tank case (ground).
WARNING
:
Use caution when working near the batteries and their connections. Remove metal rings and
watchbands that may inadvertently come in contact with the battery terminals. Severe skin
burns could result if such metal articles were shorted across the battery terminals.
X-radiation Exposure
The X-ray tube assembly produces X-radiation when energized. Never operate this device without X-ray shielding in
place. Use lead shielding and draping to protect personnel.
WARNING
:
Lead aprons, radiation monitors, and appropriate radiation shields must be utilized for the
protection of all personnel in the vicinity while performing tests. Living human anatomy should
never be used as a phantom or demonstration aid. Do not produce radiation in hallways.
CAUTION
:
Many of the PCB's in this system contain components which are sensitive to Electro-Static Discharge (ESD).
Observe ESD safety procedures.
