Grounding: – Grounding, cable selection and cable routing must be considered for electromagnetic interference-free operation. Planning considerations are discussed in the subsequent sections. • Other requirements: – Room lighting independent of the equipment power source. A batterypowered emergency lighting system is recommended. – A well-developed process connection, with or without marshalling facilities. – Effective grounding through a net of copper bars – Cable routing observing standard installation regulations. – Availability of power and other necessary utilities. – Observation of standards and legal regulations. – Sufficient free space in front of the cabinet in order to fully open the doors. For safety reasons there must always be adequate space available, even with the doors in the fully open position. For additional information regarding design considerations, see Appendix B, Power Consumption. Electro-Magnetic Compatibility The AC 800M units are intrinsically EMC compatible according to CE marking rules. For additional information regarding Electro-Magnetic Compatibility, see Appendix D, Directive Considerations.

Laying Field Cables There are no special requirements for laying field and communication cables connected to AC 800M. However: • Cables for short-distance communication without modems should always be routed at a distance of 10 cm (4 in) from other cables. • All cables connected to AC 800M should be routed at a distance of 30cm (12 in) from all power cables and 10 cm (4 in) from cables belonging to the relevant international immunity standard, class 4. Type of Field Cable Always use shielded cables for the following applications: • Communications • High-frequency pulse transmission • Low level analog signals, for example Pt100 and thermocouples Unshielded cables may be used for other applications. The signal and return conductor should be located in the same cable. Lightning Protection Industrial installations and power plants are normally provided with well-integrated grounding networks, installed as part of the power distribution system. Such installations do not require additional lightning protection unless using overhead wiring or suspended cables in an outdoor environment. However, large dispersed plants such as water supply installations and oil refineries will have an inadequate grounding system where signal cables may be routed above ground. In such cases lightning protection equipment must be installed. Should cables be discovered outside the grounding system (even at a short distance such as 10 m [9.1 yds]) lightning protection equipment must be installed.
