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

Use cable trays or a separate conduit if possible. The controller's earth should, if possible, be connected to a FUNCTIONAL EARTH rather than the mains safety earth. This will improve immunity to high frequency noise. Most modern buildings have a specific soil for this purpose.
