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. * With the exception of EN-70e, which provides a dielectric strength of only 4.6 kV AC, and does not provide any transient voltage suppression.

The EN-70 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. With its UL approval, the EN-70 is also suita- ble for devices destined for export to the North American markets. Above all, the EMOSAFE EN-70 Network Isolators are characterized by their particularly small installation size and their universal applicability. An overview of the available models can be found in section 4 SUM- MARY OF VARIANTS. For all EN-70 variants, with the exception of stand-alone types EN-70HD and EN-70e, the outgoing plug socket at the rear can be ordered either in a straight (H) or a 90 angled (V) format. With the exception of EN-70e, the EN-70 series offers a particularly effective level of device protection. Voltage spikes on individual signal conductors are eliminated by means of a supplementary TVS diode cir- cuit. These transient voltages cannot be repressed by conventional network isolators. Low-frequency signal components are strongly attenuated, so that connected devices may, for example, be protected against ground loops. 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 POTENTIAL DIFFERENCES (TECHNICAL BUILDING SYSTEMS) Computer systems, which are electrically connected with each other over significant distances via Ether- net cabling, where current flows caused by potential differences must be prevented. 3.5 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.
