Dear All,
I hope you can help me regarding the evaluation of MOOP and MOPP of a medical device. The medical device is a class 1 device with metal enclosure connected to earth. The device has 1 applied part. The applied part, has a metal enclosure, is powered with 12 V and is not connected to earth. Beyond that the device has an earthed metal touch panel with plastic front powered with 12 V. The touch panel is accessible both to user and to the patient. The internal power supply board meets 2 MOPP regarding i/p to o/p (4 kV high voltage test and 8 mm creepage and 5 mm clearance) and 1 MOPP regarding i/p to earth (1.5 kV high voltage test and 4 mm creepage and 2.5 mm clearance). My question is how shall the number of MOP be defined in the insulation diagram?
- for power supply board i/p to o/p must be 2 MOPP this is clear.
- what about the MOP between mains and the touch panel? The power board provides only 1 MOPP (between i/p to earth).
- and how shall the MOP of the applied part be defined.
Thank you for your help!
