EMC Recommendations
Use the following checklist to ensure the inverter is within proper operating ranges and
conditions.
1. The power supply to 3G3MX2 inverters must meet these specifications:
2. Installation measure:
3. Wiring:
4. Environmental conditions-when using a filter, follow these guidelines:
Location: 1000 meters or less altitude, indoors (no corrosive gas or dust)
Note on Low-voltage Directive
Ensure correct installation and wiring by following the instructions provided in Chapter 2
"Design" of this User's Manual.

3G3MX2 inverter. Refer to the instruction of the applicable external
Use a filter designed for
EMC filter.
Shielded wire (screened cable) is required for motor wiring, and the length must be 20 meter
or less.
If the motor cable length exceeds the value shown above, use output choke to avoid
unexpected problem due to the leakage current from the motor cable.
The carrier frequency setting must be 2 kHz to satisfy EMC requirements.
Separate the power input and motor wiring from the signal/process circuit wiring.
Ambient temperature: −10 to 50°C (Derating is required when the ambient temperature
exceeds 40°C)
Humidity: 20 to 90% RH (non-condensing)
Vibration: 5.9 m/sec2 (0.6 G) 10-55Hz
