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 oth-
er 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.

b. Connecting devices and noise sources to a common earth electrode
This is an earthing method to connect the device that is connected with a communications ca-
ble, other devices, and a device that could be a noise source, to a common earth electrode.
This earthing method is not recommended because the device that could be a noise source
may interfere electromagnetically with other devices.

Daisy Chain
This is an earthing method to connect the device that is connected with a communications cable,
other devices, and a device that could be a noise source using a daisy-chain topology to a common
earth electrode.
This earthing method is not recommended because the device that could be a noise source may
interfere electromagnetically with other devices.
