Figure 24: Shield connection clamp
The cable shield shall be properly connected to the IED chassis by the cable
clamp with the maximum open conductor length of 40 mm between clamp and
terminals. If double shielded cable is used, the inner cable shielding should be
connected at the external equipment end only. At the IED terminal end, the
inner shield should be isolated.
6.2 Making of Ethernet connections
6.2.1 Connecting station communication interfaces
M11720-2 v11
The numerical module (NUM) provides up to four Ethernet ports (one basic and three
optional). These ports are used for IEC 61850 or DNP3 communication. The serial
communication module (SLM) provides four optical ports which are used for LON, SPA, IEC
60870-5-103 or DNP3 communication.
• Ports X301 to X304 on the NUM module are used for IEC 61850-8-1 and IEC/UCA
61850-9-2LE communication. Ports X301/X302 and X303/X304 are to be used in pairs for
redundant communication. The optical port connectors are of LC type and the galvanic
connectors are of RJ45 type.
• Optical ports X311 A and B on the SLM module are used for SPA, IEC 60870-5-103 or DNP3
communication. The port connectors are of ST (glass) or HFBR Snap in (plastic) type.
• Optical ports X311 C and D (Tx, Rx) on the SLM module are used for LON communication.
The port connectors are of ST (glass) or HFBR Snap in (plastic) type.
