Use screened cable for all connections to BEMS controllers, data recorders, etc. To prevent ground hum loops, which can produce noise, the screen should frequently only be earthed at one end (often the controller end). Running low voltage supply and signal lines over high voltage or mains cabling is not recommended.

If at all possible, use cable trays or a different conduit. If at all possible, the controller's earth should be wired to a FUNCTIONAL EARTH rather than the mains safety earth. This will strengthen your resistance to high frequency noise. The majority of contemporary structures have a special soil for this use.
