If the earthing method used for the building is not equipotential bonding or the earthing system is un-
known, choose (a) from the earthing methods given below.
a. Installation method by connecting devices and noise sources to separate earth electrodes
This is an earthing method to separately ground an earth electrode of the device that is connected
with a communications cable or other devices and an earth electrode of a high-power device that
could be a noise source, such as a motor or inverter. Each earth electrode must be ground to 100
Ω or less.
Connect the ground lines of the device that is connected with a communications cable and other
devices as a bundle to a single earth electrode. Be sure that the earth electrode is separated by a
minimum of 10 m from any other earth electrode of a device that could be a noise source.
