Wiring diagrams

Single-phase two-wire system
* One dedicated current transformer (CT) is required for one load.

Single-phase three-wire system / Three-phase three-wire system
* Two dedicated current transformers (CT) are required for one load.

Caution for Wiring

  • 1.Terminal fastening torque should be 0.5 to 0.6N・m for M3 screw and should be 0.8 to 1.0N・m for M3.5 screw. In case of using a crimping terminal, use it with insulating sleeve applicable to M3 screw or M3.5 screw.
  • 2.To protect the device, it is necessary to install power switch and circuit breaker in the power supply circuit. 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 and measured 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.
