The ZRSG implementation should be extended to include all equipment racks and interconnecting cable paths: metal conduits, cable trays, wireways, etc. Detailed installation guidelines can be found in: EPRI TR- 102400, Volume 2, Handbook for Electromagnetic Compatibility of Digital Equipment in Power Plants, Implementation Guide for EMI Control IEC 61000, Part 5, Section 2, Electromagnetic compatibility (EMC), Installation and mitigation guidelines, Earthing and cabling IEEE Std 1100-1999, IEEE Recommended Practice for Powering and Grounding Electronic Equipment 170 Chapter 3 Installation and Maintenance Planning and Installation Guide for Tricon v9–v10 Systems Tricon Field, Power, and Ground Wiring All Tricon power distribution and safety grounding (protective earthing) must be done per the applicable national electric codes, plus the information contained in this manual, typical examples include: IEC 60364, Electrical Installations of Buildings National Fire Protection Association, 2002 Edition of the National Electrical Code Handbook Typically, the Tricon will be installed in an equipment rack or cabinet located in a control room. All wiring internal to that cabinet and leading to from that cabinet should be segregated into different types and bundled accordingly, for example: • Measurement signals - typically very sensitive, low voltage signals from sensors: RTDs, TCs, speed or flow sensors, etc. These signals will typically require shielded twisted pair cabling. • Measurement and low power control signals - typically sensitive, low voltage signals to/form intelligent sensors or control devices: 4-20 ma loops, 24 VDC discrete signals, etc. These signals will typically require twisted pair cabling. • High power control signals and conditioned power distribution - typically not sensitive, higher voltage signals: 48-120 volt discrete signals, 24-120 VDC I/O power distribution, etc. These signals should always use twisted pair cabling. • Input coming power and misc. circuits - typically noisy, higher power circuits - 115 VAC discrete signals, AC power distribution, cabinet fans or lights, etc. These signals should always use twisted pair cabling, and the Grounding Electrode Conductor (the green wire) should be twisted along with the power leads wherever possible. • Earth bonding connections. All cable routing and installation should be done to minimize EMI, detailed guidelines can be found in: EPRI TR- 102400, Volume 2, Handbook for Electromagnetic Compatibility of Digital Equipment in Power Plants, Implementation Guide for EMI Control IEC 61000-5-2, Electromagnetic compatibility (EMC), Installation and mitigation guidelines, Earthing and cabling IEEE Std 1100-1999, IEEE Recommended Practice for Powering and Grounding Electronic Equipment Typical guidelines include the following: • Use ferrous metal cabinets, cable trays, and conduits. • When the RS-485 I/O Bus is used to connect to a remote Expansion Chassis, the I/O Bus cables must be routed in dedicated metallic conduit or equivalently isolated from other noise sources. • Electrically bond all surfaces of the cabinet and it's contents together with multiple conductive metal strapping, not simple wire. Particular attention should be paid to doors, and removable panels. In turn the cabinet must be bonded to the control room or plant safety ground system or ZRSG. Installation Guidelines 171 Planning and Installation Guide for Tricon v9–v10 Systems • Routinely use twisted pair cabling; use shielded twisted pair cabling for all sensitive signals. Allow the minimum amount of un-twisted wire that accommodates connection. • Signals of different types should never be bundled together. • Bundles of different types should be separated by a minimum of 10 times the largest lead diameter. • Bundles of different types of signals should only cross at right angles to each other. • All wires and/or bundles should be routed along the ZRSG; for example, along the cabinet walls, within a cable tray or conduit, along building steel or the floor ground grid. • Where an inline filter or power conditioning is used, the input and output leads should never be routed in the same bundle.
