18 19Wiring• In case of 3-Phase 200 VIn wiring to power supply (outside of equipment) from MCCB, use an electric wire of1.6 mm diameter (2.0 mm 2 ) or more both for main circuit and grounding.Please ground with grounding resistance less than 100 Ω.Do not tighten the ground wires together, but connect them individually.Fastening torque of earth screws to be 0.8 to 1.2 N·m.When extending the motorwires, use the optionalmotor extension cable.(See page 75)When extending the motorwires, use the optionalmotor extension cable.(See page 75)• In case of single phase 100, 200 VIn wiring to power supply (outside of equipment) from MCCB, use an electric wire of1.6 mm diameter (2.0 mm 2 ) or more both for main circuit and grounding.Please ground with grounding resistance less than 100 Ω.Do not tighten the ground wires together, but connect them individually.Fastening torque of earth screws to be 0.8 to 1.2 N·m.Brushless amplifierPowersupplyinputL1L2L3Be sure to ground the grounding terminal.MCCBMolded Case(Circuit Breaker)GroundingBrushless amplifierPowersupplyinputL1L2MCCBMolded Case(Circuit Breaker)GroundingBe sure to ground the grounding terminal.NoisefilterNoisefilterWiringStandard wiring diagramFunction of terminalTerminal for power supply (POWER)Part number of terminal block: 0138-7603 (DINKLE)TerminalsymbolTerminalname Terminal explanationL3 Terminal forpower supplyinputConnect the terminal to commercial power supply conforming tovoltage specification. When you use singlephase, connect the main power between L1 and L2 terminals.L2L1The lower side of product is L1.How to wiring:Please use a single wire or rod terminal and insert as far into the connection hole.Recommended rod terminal: TGN TC-1.25-9T(NICHIFU), Applicable wire size: AWG20 to 16.In case of single wire: Strip length 10 mm (reference): Applicable wire size: AWG20 to 14.10 mm* Please check tools etc. necessary for terminal crimp on the home page of terminalmanufacturer or contact terminal manufacturer.* Since the strip length of the wire depends on the type of wire etc., please decide theoptimum strip length according to the processing condition.CAUTION: To prevent unforeseen circumstances due to poor contact etc., install and wire sothat no stress such as pulling is applied to the terminal block through the cable.How to remove wiring: Right figureUsing a flathead screwdriver with a blade width of 2.6 mm,push the Wire extraction button of the terminal block verti-cally and remove the electric wire. Be careful not to applyexcessive force at this time. (Approximately 20 N or less)
