Wiring of power supply, CT, and measurement voltage input

Wiring the power supply
For safety purposes, turn off the mains power and the breaker to ensure there is no power supply while you are working.

• The terminal is the push-in type. Also read “Cautions when connecting the Push-In Plus terminal ” when wiring.
• To wire with the power supply terminal, use AWG20-16 wire (with a cross-section of 0.5 to 1.5 mm2).
• Peel the wire-coating by 10 mm when using a ferrule terminal and by 8 mm when not using it.
• Use a ferrule terminal with a conductor portion 8mm long.

Wiring the CTs
For safety purposes, turn off the mains power and the breaker to ensure there is no power supply while you are working.

• You will need 3 CTs to measure 3-phase 4-wire, 2 CTs to measure 1-phase 3-wire or 3-phase 3-wire, and 1 CT to measure 1-phase 2-wire.
• CTs have polarity, so confirm the current directions at the power supply side (K) and load side (L) before wiring the CTs. If the direction is not appropriate, power cannot be measured correctly.
• To wire the CT input terminals, use AWG18-14 wire (with a cross-section of 0.75 to 2.0 mm2) and crimping terminals of the round shape or Y-shape (5.8mm wide or less) compatible with the M3 screw.
• The recommended torque for screwing the 3mm screws onto the terminal panel is 0.5 to 0.58 N·m. Make sure the crimping terminal is pushed all the way in and tightened firmly. After fixing the wiring, confirm that the wire is fixed securely.

Wiring the measurement voltage input
For safety purposes, turn off the mains power and the breaker to ensure there is no power supply while you are working.

• Wire correctly so the phase sequence is correct. You will be unable to measure the power and energy correctly if you fail to do so.
• To wire with th2e measurement voltage input terminal, use AWG18-14 electric wire (with a cross-section of 0.75-2.0mm ) and crimping terminals ofthe round shape or Y-shape (5.8mm wide or less) compatible with the M3 screw.
• The recommended fastening torque of the M3 terminal screw is 0.5 to 0.58 N·m. Make sure the ferrule terminal is pushed all the way in and tightened firmly. After fixing the wiring, confirm that the wire is fixed securely.

• The diagram at right shows the relationship between the wiring table and the terminals on the main unit.
• For details about how to wire the CTs, connect the S1 terminal to the CT power supply side (K) and the S2 terminal to the CT load side (L).For the distinction between the power supply side (K) and load side (L) of the CT,refer to the manual of the CTs you are using.

Pulse output wiring

This unit is equipped with 4 pulse output terminals. The common terminal is used commonly.

• The terminal is the push-in type. Also read “Cautions when connecting the Push-In Plus terminal ” when wiring.
• Do not directly connect an external power source to OUT or COM. Make sure the load is connected.
• To wire with the pulse output terminal, use AWG24-16 twisted or solid wire (with a cross-section of 0.25 to 1.5 mm2).
• Peel the wire-coating by 10 mm when using a ferrule terminal and by 8 mm when not using it.
• Use a ferrule terminal with a conductor portion 8mm long.
• To avoid the influence of noise, use separate wiring for the signals and for the power.
• Output for circuit A is allocated to OUT1, circuit B to OUT2, circuit C to OUT3, and circuit D to OUT4, and these allocations are fixed.

RS-485 wiring
The configuration of the connection should be either 1:1 or 1:N. If the 1:N connection is Modbus, up to 99 KM-N3 can be connected. If CompoWay/F, up to 31 KM-N3 can be connected.

The terminal is the push-in type. Also read “Cautions when connecting the Push-In Plus terminal ” when wiring.There is no FG terminal on KM-N3. Connect only the

• wire and – wire of RS-485. Use twisted pair cables.

  • To wire with the RS-485 terminal, use twisted or solid wire of AWG24-16 (with a cross-section of 0.25 to 1.5 mm2).
  • Peel the wire-coating by 10 mm when using a ferrule terminal and by 8 mm when not using it.
  • Use a ferrule terminal with a conductor portion 8mm long.
  • To avoid the influence of noise, use separate wiring for the RS-485 communications and for the power.
  • The maximum transmission distance is 1200m.
  • Irrespective of the transmission distance and number of units connected, perform communications checks with the actual units.

Termination settings

This unit is equipped with a terminating resistor inside the main unit. On the unit that is the terminator for communications, short the RS-485 – terminal and the RS-485 E terminal with a cable. Connect with the internal terminating resistor.
If the host device you are using does not have its own built in terminating resistor, connect a terminating resistor to the host device. The terminating resistance is 120Ω (1/2W).
Do not wire in a terminating resistor terminal on KM-N3 that are along the transmission path. This can caused communication failures.
