Hitachi EMC Recommendations

WARNING: This equipment should be installed, adjusted, and serviced by qualified
personal familiar with construction and operation of the equipment and the hazards
involved. Failure to observe this precaution could result in bodily injury.
Use the following checklist to ensure the inverter is within proper operating ranges and
conditions.
1.The power supply to X200 inverters must meet these specifications:
xVoltage fluctuation ±10% or less
xVoltage imbalance ±3% or less
xFrequency variation ±4% or less
xVoltage distortion THD = 10% or less
2.Installation measure:
xUse a filter designed for X200 inverter.
3.Wiring:
xShielded wire (screened cable) is required for motor wiring, and the length must
be less than 5 meters.
xThe carrier frequency setting must be less than 5 kHz to satisfy EMC
requirements.
xSeparate the power input and motor wiring from the signal/process circuit
wiring.
4.Environmental conditions—when using a filter, follow these guidelines:
xAmbient temperature: –10 to 40 °C
xHumidity: 20 to 90% RH (non-condensing)
xVibration: 5.9 m/sec2 (0.6 G) 10 ~ 55Hz
xLocation: 1000 meters or less altitude, indoors (no corrosive gas or dust)
