3-2-3 Grounding

The NT600S has a Grounding terminal .

Note 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 mm2).

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.

Caution Carry out class 3 grounding (grounding wire must be less than 100￿) before con- necting the power supply. Otherwise there will be a danger of electric shock.
