906-0731-04-01 Rev. C ZOLL Ventilator Service Manual 5–4
Electrical Safety Testing Procedure
Visual Inspection of the device:
• Review all labeling to ensure that any safety or classification markers are legible and in-tact.
• Ensure that housing shows no signs of excessive damage, cracks or structural compromise.
• Inspect all cables, including the external power supply looking for signs of excessive wear or damage to the
cable integrity.
Leakage Testing :
• The chassis of the 731 Series ventilator is electrically isolated from AC power. Enclosure leakage testing of
all exposed metal components on the device should be utilized in order to verify the device remains
properly insulated. Use the following values for enclosure leakage in accordance with IEC 60601-1.
NOTE:
Perform this procedure in accordance with your local protocols and standards. The leakage limits provided below
are taken from the IEC 60601-1 for reference.
IEC 60601-1 LEAKAGE TEST LIMITS
Normal Condition Single Fault Condition
Enclosure Leakage
100 µA 500 µA
NOTE:
A diagram of all exposed touch points can be found on the following page.
NOTE:
The SPO2 sensor is optically isolated from the system with no exposed metal components in contact with the
patient. It is not a requirement to test the SPO2 sensor as an applied part during this procedure.
