• For grounding, use a dedicated ground wire (2 mm
2
or larger) and apply Class D grounding
(third class grounding: 100
Ω or less grounding resistance).
• Do not share the Sensor controller’s ground with other equipment or ground the Sensor con-
troller to the metal structure of a building. Doing so may worsen operation. Whenever possi-
ble, use an independent ground (with the ground pole separated by a minimum of 10 m from
any other ground pole).
• Ground to 100 Ω or less, and if possible use a separate ground from those of other devices.
(Refer to figure (a) in the diagram below.)
• If using an independent ground is not possible, then use a common ground as shown in fig-
ure (b). Connect to the ground pole of the other device.
