KW2G / KW2G-H Eco-POWER METER103.4 Terminal arrangementBe sure to wire correctly according to the terminal arrangement and wiringdiagrams. After completing wiring, be sure to attach the terminal cover forsafety reasons.3.4.1 Main unit (common to AKW2010G and AKW2020G)No. Function ScrewTop① P1 Measured voltage inputP1-P0 common to operatingpower supply M3.5② P0③ P2④ NC VacantMid⑤ ＋ Pulse outputM3⑥ －⑦ ＋ Pulse input⑧ －Bottom⑨ ＋RS485⑩ －⑪ EThe input voltage to each terminal is as follows.Terminal Phase and wire Terminal Input voltageMeasuredvoltage inputSingle-phase,two-wire①－②(P1-P0) 100-240VAC (100-240V～) (Line voltage)Single-phase,three-wire①－②－③(P1-P0-P2)100-120VAC(100-120V～：3W) (Phase voltage)Three-phase,three-wire①－②－③(P1-P0-P2)100-240VAC(100-240V 3～) (Line voltage)Caution for Wiring1) Terminal fastening torque should be 0.5 to 0.6N･m for M3 screw and should be 0.8 to 1.0N･m forM3.5 screw. In case of using a crimping terminal, use it with insulating sleeve applicable to M3 screwor M3.5 screw.2) To protect the device, it is necessary to install power switch and circuit breaker in the power supplycircuit. And this has no built-in power switch, circuit breaker or fuse for measured voltage input parts.Therefore it is necessary to install them in the circuit near this unit.3) We recommend a wire with the cross section of 0.75 to 1.25mm2 for power supply line andmeasured voltage input line.4) Use with 10m or less of the input line and 100m or less of the output line.5) Use flame-resistant cable for each wiring. width: 6.6mm or less width: 5.8mm or less① ② ③ ④⑤ ⑥ ⑦ ⑧⑨ ⑩ ⑪
