Cautions during Use

  • Follow instructions in ‘Cautions during Use’.
    Otherwise, It may cause unexpected accidents.

  • Power supply should be insulated and limited voltage / current or Class 2, SELV power supply device.

  • Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power.

  • Keep away from high voltage lines or power lines to prevent inductive noise. In case installing power line and input signal line closely, use line filter or varistor at power line and shielded wire at input signal line.
    Do not use near the equipment which generates strong magnetic force or high frequency noise.

Connections of Applications

DC voltmeter connection
  • V1 (measuring voltage): ≤ 300 VDC

  • V1 (measuring voltage): ≥ 300 VDC

Connections of Applications

AC voltmeter connection
  • AC voltmeter connection

  • V1 (measuring voltage): ≥ 400 VAC
    Connections of Applications

DC ammeter connection
  • I (measuring current): ≤ DC 2 A

  • I (measuring current): ≥ DC 2 A

AC ammeter connection
  • I (measuring current): ≤ AC 5 A

  • I (measuring current): ≥ AC 5 A

Simultaneous connection of voltmeter and ammeter
  • A: Compared to measurement input range, higher measuring voltage needs a multiplier and lower measuring voltage needs a shunts.
  • Connect the separated power supply each.
  • (-) terminal of the power and (-) terminal of measurement input are shorted. In case of using same power supply, measurement error or overcurrent may occur.

  • B: When measuring higher current than measurement input, use a shunt for DC current and a current transformed (C.T) for AC current.
Power meter connection
Rotation / Speed meter connection
  • Tacho generator (T.G) : This generator makes a voltage in proportion to revolution speed of motor. The panel meter receives the voltage and displays the number of revolution. There are AC voltage and DC voltage for output voltage.
