WiringKW2M-A/X User's Manual 11◆Applicable wire (a crimp-type terminal is recommended.)･Stripping length: 7 to 8mm・Power supply/Measured voltageScrew type: M3Tightening torque: 0.5 to 0.6N･mSectional area: single /stranded wire 0.13 to 6mm2 (AWG26 to12)・for 2pcs.single/stranded wire 2pcs.×0.5 to 2.5mm2 (AWG20 to 12)・Measured current (CT input)Screw size: Push-in typeSectional area: single /stranded wire 0.13 to 1.5mm2 (AWG24 to16)*Use a wire suitable for the current to be measured.・RS485 communicationScrew size: Push-in typeSectional area: single /stranded wire 0.13 to 1.5mm2 (AWG24 to16)*Use a shielded wire for RS485 communication.・Output/InputScrew size: Push-in typeSectional area: single /stranded wire 0.13 to 1.5mm2 (AWG24 to16)4.2 Measured circuit・It is possible to use two different measurement voltages (2 circuits of same system with 1 unit).・Each unit (main unit, expansion unit (power measurement, power measurement + pulse output)) canmeasure 2 circuits of a single-phase two-wire system, and 1 circuit of a single-phase three-wire systemor three-phase three-wire system. Each unit can be used with a different phase and wire system.However, check the wiring carefully.・It is not possible to take measurement with only the expansion unit. Every expansion unit must beconnected to a main unit.Up to 3 expansion units can be connected to 1 main unit.*Power source system・The power source system is the electrical power system from one power source (normally onetransformer).･KW2M-A can measure 1-system max. 24-circuit of 1P2W system and 1-system max. 8-circuit of 1P3Wand 3P3W system by connecting a main unit and expansion units.・In order to measure several systems, it is necessary to use one main unit for each system.
