Protective Earth
Chapter 1 - Safety 7
Protective Earth
To protect hospital personnel and the patient, the cabinet must be
grounded. Accordingly, the receiver is equipped with a 3-wire power
cable which grounds it to the power line ground when plugged into an
appropriate 3-wire receptacle. Do not use a 3-wire to 2-wire adapter with
the receiver. Any interruption of the protective earth grounding will cause
a potential shock hazard that could result in serious personal injury.
Whenever it is likely that the protection has been impaired, the receiver
must be made inoperative and be secured against any unintended
operation.
The patient cable must be positioned so that it does not come into
contact with any other electrical equipment.
Before operation, make sure that the receiver is free from condensation.
This can form when equipment is moved from one building to another,
and is exposed to moisture and differences in temperature.
