Grounding of Coaxial Cable
Ground the shield conductors of the coaxial cables at one point with 100 Ω or less earthing for
each segment. For Ethernet control LAN, the grounding terminal is used for one point grounding.
When repeaters are used to install additional coaxial cable segments, ground each segment at one
point. When the transmission line is in redundant configuration, ground each of the A system and
B system at one point.
