Be sure to wire correctly according to the terminal arrangement and wiring diagrams. 2. A DIN rail terminal socket (AT8-DF11K) should be used for 11-pin type Eco-POWER METER.  Caution for Wiring (1) Terminal fastening torque should be approx. 1.0 N·m. In case of using a crimping terminal, with insulating sleeve applicable to M3.5 screw. (Refer to the below.) 3.7mm 6.6mm or less  Terminal arrangement * Round terminals cannot be used in KW4M. Use Y shape terminals. (2) To protect the device, it is necessary to install power switch and circuit breaker in operating power supply circuit. Therefore it is necessary to install them in the circuit near main unit. (3) We recommend a wire with the cross section of 0.75 to 1.25 mm2 for operating power supply line and measured voltage input line. (4) Use fire resistant electrical wire (UL electrical wire, etc.) Be sure to wire correctly according to the wiring diagram. The input (applied) voltage to each pin (terminal) is as follows.
