If possible segregate the signal cable from Power Cables; allow a 1 metre (3 feet) distance from such cables.
Do not run signal cables in parallel with power cables and only cross such cables at right angles.
The ground connection conductor should have sufficient cross-sectional area to ensure a low impedance path to
attenuate RF interference.
