The Network Isolators prevent current flow resulting from differences in electrical potentials, and also protect connected devices and their users from stray external voltages and power surges which may be directly or inductively coupled onto the network lines by causes such as installation errors, lightning, switching operations, and electrostatic discharge. Built into a medical electrical (ME) product, the EMOSAFE EN-50 Network Isolator facilitates the safe Ethernet connection of this ME product within the patient environment. The EN-50 satisfies all construc- rd tion requirements of IEC 60601-1 (3 Edition) in the formation of two means of patient protection (MOPP) within the network interface, thereby practically eliminating the risk of electrical shocks arising from such stray external voltages at the network connection.

Devices and cables attached to un- grounded Ethernet interfaces can hereby be the cause of electromagnetic disturbances. To avoid this problem, the EN-50 series of Network Isolators provides an electrical connection to the otherwise sepa- rated earth connection via an integrated resistor network and parallel Y-Class capacitors. This results in a greatly reduced risk of radiated and received electromagnetic interference, without compromising the protective effect of the Network Isolator. With its highly resistive shielding connection, the EN-50 also enables the slow and gentle equalisation of potential voltage differences. The EN-50 is further distinguished by its gigabit Ethernet capability and its robust construction. The op- tional Yamaichi Y-Con connection system simplifies the plugging and unplugging process, increases the mechanical restraining strength, and also reduces the risk of accidental human contact of the conductive surfaces, thus reducing the risk of potentially dangerous electrical discharge through the ME operator or the patient. The Y-Con connection is also fully compatible with conventional Ethernet connectors. As UL Recognized Components, the EN-50 Network Isolators are also suitable for inclusion in devices des- tined for export in the North American markets. All variants of the EN-50 family can be ordered with the internal Ethernet connection in either a horizontal (H), or a 90 vertical (V) configuration. EMOSAFE Network Isolators transmit high-frequency signals through the principle of electromagnetic in- duction. Because of this, they do not require their own power supplies. There are no software drivers to be installed. 3 APPLICATIONS 3.1 PATIENT PROTECTION Electrical separation of Ethernet interfaces of medical electrical (ME) devices and systems, where patients must be protected from dangerous leakage currents, in conformity with applicable standards. 3.2 EQUIPMENT PROTECTION Applications, in which valuable devices or those requiring special protection need to be protected against ripple, mains hum, and surge voltages from the network periphery. 3.3 MEASUREMENT TECHNOLOGY Electrical measuring and monitoring equipment, which needs to be protected against external voltages and interference voltages arising from the Ethernet periphery. 3.4 AUDIO Audio applications, in which the transmission of low frequency alternating current voltages (mains hum) over the network connection is to be reduced to an imperceptible level.
