The SJ700 series inverter conforms to the requirements of Electromagnetic Compatibility
2
(EMC) Directive (2004/108/EC). However, when using the inverter in Europe, you must
comply with the following specifications and requirements to meet the EMC Directive and
other standards in Europe:
WARNING: This equipment must be installed, adjusted, and maintained by qualified
engineers who have expert knowledge of electric work, inverter operation, and the hazardous
circumstances that can occur. Otherwise, personal injury may result.
Use the following checklist to ensure the inverter is within proper operating ranges and
conditions.
1. Power supply requirements
a. Voltage fluctuation must be -15% to +10% or less.
b. Voltage imbalance must be ±3% or less.
c. Frequency variation must be ±4% or less
d. Total harmonic distortion (THD) of voltage must be ±10% or less.
2. Installation requirement
a. A special filter intended for the SJ700
3. Wiring requirements
a. A shielded wire (screened cable)must be used for motor wiring, and the length must be
according to the following table below.
b. The carrier frequency must be set according to the following table to meet an EMC
requirement.
c. The main circuit wiring must be separated from the control circuit wiring.
4. Environmental requirements (to be met when a filter is used)
a. Ambient temperature must be within the range –10°C to 40°C.
b. Relative humidity must be within the range 20% to 90% (non-condensing).
c. Vibrations must be
2
5.9 m/sec (0.6 G) (10 to 55Hz) or less (0.4 to 22kW).
2
2.94 m/sec (0.3 G) (10 to 55Hz) or less (30 to 150kW).
d. The inverter must be installed indoors (not exposed to corrosive gases and dust) at an
altitude of 1,000 m or less.
