3. WIRING3.7 Wiring Cautions(1) Lay wiring as far as possible from electrical noisesources such as large transformers, motors and powersupplies.(2) It is recommended that crimp-on type solderless lugs beused for large wire ends.(3) For general use, it is recommended that conduits andducts or racks be used to protect wiring from water ormechanical damage. A rigid steel conduit or flexiblemetal conduit is recommended. See Figure 3.9.3.8 GroundingIMPORTANTWhen a lightning protector (option code: /A) isselected, use a grounding resistance of 10Ω or less.(1) The grounding terminals are located on the inside andoutside of the terminal area. Either terminal may beused.(2) For pulse output version, ground the flowmeter. Alsoground the shielded cable between the converter and thepulse receiver.(3) Grounding should satisfy Class D requirements (groundresistance 100Ω or less).(4) Use 600V PVC insulated wire for grounding.Integral TypeGroundingterminalsF030801.EPSF030701.EPSFigure 3.10Figure 3.93-7 IM 01F06A00-01EN
