More importantly, is your system grounded? All motor frames, the metal structure of the machine and any electrical cabinets/boxes etc should all be bonded together and connected to a good earth ground. On a well grounded system all ground wires are taken back to a common ground plate together with the main ground conductor. Also any power supplies that have grounded commons should also be connected at this point, as well as any outer shields of signal wiring etc.
