3-2-3 Grounding
The NT600S has a Grounding terminal .
To prevent malfunctions due to excessive noise, and to prevent electric shock,
carry out class 3 grounding (grounding resistance of 100

or less) using a spe-
cial-purpose grounding cable (wire of at least 2 mm 2 ).
Grounding wire length should be less than 20 m.
Note that if grounding wire is used in common with other equipment, or if it is con-
nected to a beam of a building, for example, the NT600S might be adversely af-
fected by this grounding.
