1 ENGLISH EMOSAFE EN-100 Product Data Sheet Network Isolators for PCB assembly November GENERAL DESCRIPTION The EMOSAFE EN-100 Network Isolator interrupts all galvanically conducting connections (conductors and shielding) between the Ethernet input socket and the Ethernet circuit of the device being protected. They prevent potential equalisation currents and protect devices and their users from transient excess voltages which have been coupled directly or inductively into the Ethernet network line through errors in installation, lightning strikes, switching operations, electrostatic discharges and so on. EMOSAFE EN-100 Network Isolators are meant to be integrated into the PCB of the device being protected. There are models available for plug-in assembly with socket strips and models that can be permanently soldered. Their extremely compact design also allows them to be used in situations where there is very limited space. A summary of the available variants can be found in Section 4 SUMMARY OF VARIANTS All EN-100 models provide especially effective device protection thanks to the implementation of additional TVS diode circuitry. Voltage spikes on single conductors cannot be suppressed using conventional network isolators However, even these are eliminated when using the EN-100. Devices in the EN-100 series meet the requirements of IEC (3 rd Edition) and IEC and as such are suitable for providing the galvanic separation of Ethernet interfaces for devices used in the field of medicine. EMOSAFE Network Isolators transmit high-frequency AC voltages using the principle of electromagnetic induction in the frequency range used for data transmission. Due to this transmission principle, they do not require their own power supply. The installation of drivers is not required. Low-frequency signal components are strongly attenuated, so that connected devices may, for example, be protected against ground loops.

5 5.1.2 EN-100T FITTING DIMENSIONS The pin connectors can be soldered directly into the PCB or, as illustrated, be plugged into a socket strip. This dimensioned drawing illustrates a socket strip with a height of 4.2 mm. The assembly height is reduced by this amount if a socket strip is not used. PD 1056-V20 Page 5/ EMO Systems GmbH

6 5.1.3 EN-100T PCB LAYOUT No conducting paths should be placed in the shaded area as this would reduce the leakage distance to inadmissible values. The dimensions given for the shaded area refer to the requirements for the provision of two protective measures for patient protection for devices with a voltage rating of 250 V(400 V). However, the actual requirements for the clearance and leakage distance vary, and have to be determined and checked depending on the device. The assembly of the Network Isolators in a manner that satisfies requirements and the relevant standards is the responsibility of the device manufacturer. PD 1056-V20 Page 6/ EMO Systems GmbH

Procedures using a reflow oven or using wave soldering are not allowed as this may cause thermal damage to the potting material within the transformer component. Avoid temperatures of more than 85 C to prevent thermal stress to the transformer component. PD 1056-V20 Page 15/ EMO Systems GmbH

16 7 INSTRUCTIONS FOR USE The EN-100 Network Isolator has been designed for data transmission in the frequency range of 0.3 to 100 MHz. Lower frequencies are strongly attenuated. For this reason, it is generally not possible to transmit the signals from nurse call systems, telephone systems or analogue audio or video signals over a Network Isolator. The EN-100 Network Isolator can be used in a Power over Ethernet (PoE) network without restriction (however PoE devices downstream of the galvanic separation cannot be supplied with power). 8 SAFETY NOTICE 8.1 SAFETY INSPECTIONS The test interval, as well as the requirements to be met for both regular safety inspections and post-repair inspections will then be specified for the interface to be protected by the organisation responsible based upon the applicable standards for this system. 8.2 CLEARANCE AND LEAKAGE DISTANCES The PCB layout and device design of devices that use the EN-100 are to be done such that the applicable standards (e.g. IEC ) for the required clearance and leakage distances are maintained.
