4.11 Grounding
(a) Grounding should satisfy KS requirements (grounding resistance, 10 Ohm or less). Grounding is
required below 10 Ohm for explosionproof and intrinsic safety.
[Note] In case of with Built-in Lightening Protector, Grounding should satisfy Special KS
requirements (grounding resistance, 10 Ohm or less)
(b) There are ground terminal on the inside and outside of the terminal box. Either of these
terminals may be used.
(c) Use 600V grade PVC insulated wire for grounding.
