4.2.3  Grounding

(1)  Provide grounding with a ground resistance of 

100Ω.

(2)  Grounding terminals are provided inside and 

outside of the terminal box. Use either terminal.

(3)  Use 600V PVC insulated wire for grounding 

wiring.

4.3  Intrinsically Safe Type Wiring

The wiring of the intrinsically safe circuit between 

the converter and the safety barrier must be kept 

routed with sufficient physical separation from other 

circuits so as not to be affected by electromagnetic 

induction, etc., and should be implemented using 

metallic conduit or shielded cable.
