The use of a network isolator enables the galvanic isolation of a copper-guided Ethernet data line and thus prevents the transmission of unwanted voltages and currents between the parts of an electrical system.
A network isolator in the medical field / medical network disconnector serves to protect the patient from leakage currents. The network connection between an active medical device and an Ethernet network or a non-medical device, such as an office PC or laptop, is safely galvanically isolated in accordance with the IEC EN 60601-1 standard (3rd edition) for medical electrical devices and systems.
Why a single network insulator cannot be a medical device and what an operator should know.
What does a network insulator do and why does it have to be used?
Installation errors, ageing processes, environmental influences or moisture can make cable sheaths brittle or fragile. The unwanted electrical connection to other live parts can lead to high overvoltages and voltage peaks for a short time and lead to a fault within the electrical system.
Network isulators must be used wherever electrically conductive connections via network cables are not permitted. This can be in commercial as well as in public and private areas. The usual areas of application are:

Wird ein Medizinprodukt mit einem Nicht-ME-Gerät, wie z.B. einem Drucker verbunden, muss die erstellte Datenleitung entsprechend den Anforderungen der IEC 60601-1 bzw. EN 60601-1 galvanisch getrennt werden und ein Netzwerkisolator eingesetzt werden.
IEC 60601-1:2005+A1:2012 (Edition 3.1) - Background knowledge on the international standard for medical electrical equipment and systems. This standard is an international standard for medical electrical equipment. It was published in August 2012 and is a revision of the basic standard IEC 60601-1 from December 2005. (European equivalent: EN 60601-1:2006+A1:2013).
EN 60601-1-2:2015 - Part 1-2: Electromagnetic compatibility of medical electrical equipment. Definition.
The IEC 60601-1:2005+A1:2012+A2:2020 standard was published in August 2020. It contains the general specifications for basic safety and essential performance characteristics for medical electrical equipment and medical electrical systems.
CE marking of network isolators. Devices for galvanic isolation of Ethernet data signals, so-called network isolators, are used as part of a medical electrical system consisting of active medical products (e.g. ultrasound or endoscope) and not medical products (e.g. computers, switches).
