Global Documentation H35x/EN GL/D23 MiCOM H35x Page 7/38 The recommended minimum protective conductor (earth) wire size is 2.5 mm² (3.3 mm² for North America) unless otherwise stated in the technical data section of the equipment documentation, or otherwise required by local or country wiring regulations.
H35x/EN GL/D23 Global Documentation Page 8/38 MiCOM H35x Technical specifications for safety Unless otherwise stated in the equipment technical manual, the following data is applicable. 1.5.1 Protective fuse rating The recommended maximum rating of the external protective fuse for equipments is 16A, high rupture capacity (HRC) Red Spot type NIT, or TIA, or equivalent.
Global Documentation H35x/EN GL/D23 MiCOM H35x Page 9/38 More information on safe working procedures for all electronic equipment can be found in IEC 60147-0F and BS5783. If you are making measurements on the internal electronic circuitry of any equipment in service, it is preferable that you are earthed to the case with a conductive wrist strap.

On the media side, MiCOM H35x supports 10BaseT, 100BaseTX and 100BaseFX as specified by the IEEE 802.3 standard. The MiCOM H35x is a plug-and-play device. It can run with the factory settings. However, to adapt the switch to your application, you only need to configure the switch number using the...
The MiCOM H35x is designed to be an Ethernet switch with a DIN RAIL mounting. MiCOM H35x Product Range The MiCOM H35x range is dedicated to ultra fast redundant Ethernet rings, and is defined by the type of Ethernet connector. All the MiCOM H35x equipment range has at least two copper connections via RJ45 connectors, with speed automatically adjusted by the external emitters to 10 or 100 Mbps.
Global Documentation H35x/EN GL/D23 MiCOM H35x Page 13/38 3.2.2 MiCOM Hx5x Ethernet switch with self-healing ring facilities The MiCOM Hx5x is a standard IEEE802.3 Ethernet switch enhanced with the self-healing manager (SHM). The diagram below shows the internal architecture of such a device.
The copper ports are half/full duplex and auto-sense the transmission speed. They will auto- negotiate with the connected device to determine the optimal speed. When the connected device is only capable of transmitting at 10 Mbps, the MiCOM H35x follows at 10 Mbps.
Address lookup Each Ethernet device inserts its unique “MAC address” into each message it sends. The port on the MiCOM H35x used for a given MAC address is automatically learnt when a frame is received from that address. Once an address is learnt, the MiCOM H35x will forward frames to the appropriate port.

Page 29/38 Ethernet Connection The Ethernet-based communication available in the MiCOM H35x uses either optical fiber media (ST/SC/LC connector) or 4 twisted pair cable. If the equipment is located at a long distance (>100 m for RJ45) from the communication equipment or multiplexer, or if the cables run through a noisy area, then optical communication should be used to interconnect the IEDs and the communication equipment.
