Hello all, first time poster here!
This clause has been addressed a lot but I am still confused about a couple of things regarding our application.
We have a protectively earthed medical device that can (but is not intended to) come into contact with the patient. The device has an external AC/DC 24V supply such that the internal working voltage of the device is 24V.
This device has two SIP/SOP ports:
Our accompanying documents state that additional equipment must comply with relevant IEC/ISO standards and all configurations should comply with the requirements for medical electrical systems.
My questions are regarding the part of the clause "...of any voltage or current from other electrical equipment that is permitted to be connected..." :
Thanks!
This clause has been addressed a lot but I am still confused about a couple of things regarding our application.
We have a protectively earthed medical device that can (but is not intended to) come into contact with the patient. The device has an external AC/DC 24V supply such that the internal working voltage of the device is 24V.
This device has two SIP/SOP ports:
- Standard RJ45 ethernet for connection to hospital network or another system that we make. The other system has mains input (internal AC/DC supply).
- Another network connection (proprietary connector on our side) intended to only be connected to a specific device that has an external AC/DC 24V supply. This other device unfortunately only has a standard RJ45 input so technically the cable could also be connected to other unintended devices.
Our accompanying documents state that additional equipment must comply with relevant IEC/ISO standards and all configurations should comply with the requirements for medical electrical systems.
My questions are regarding the part of the clause "...of any voltage or current from other electrical equipment that is permitted to be connected..." :
- Does this imply that application of any working voltage of any permitted device is Normal Condition, or just the signal/dc voltages we expect on the port? For example, for the RJ45 port the connected device could have a mains input so application of mains voltage to the RJ45 is Normal Condition?
- Is it reasonable to place an explicit restriction in the documentation for the other port, such that it only be allowed to be connected to the one specific intended device, despite the other end of the cable having a standard connector? If we could, would this lower the MOPP requirements of this port to 24V, as that is the working voltage of the other device?
Thanks!
