For all connections to BEMS controllers, data recorders, etc., use screened cable. The screen should typically only be earthed at one end to prevent ground hum loops, which can cause noise (often the controller end). It is not advised to run low voltage supply and signal lines over high voltage or mains cabling.

Use a different conduit or cable trays if at all possible. As opposed to the mains safety earth, the controller's earth should, whenever possible, be wired to a FUNCTIONAL EARTH. Your resistance to high frequency noise will be boosted as a result. Most modern buildings have a specific soil for this purpose.
