Caution for EMC (Electromagnetic Compatibility) (0.4kW-150kW)
The SJ700D series inverter conforms to the requirements of Electromagnetic Compatibility (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.
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.
The integrated filter in the SJ700D series inverter must be enabled. (See chapter 2 Installation andWiring)
* When using the specific external filter for the SJ700D series inverter, please refer to the instruction
described in the dedicated guide book for the filter.
3. Wiring requirements
a.
A shielded wire (screened cable) must be used for motor wiring, and the length of the cable must be
according to the following table (Table 1).
b.
The carrier frequency must be set according to the following table to meet an EMC requirement (Table 1).
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 +50°C.
b.
Relative humidity must be within the range 20% to 90% (non-condensing).
c.
Vibrations must be 5.9 m/s
d.
The inverter must be installed indoors (not exposed to corrosive gases and dust) at an altitude of 1,000 m
or less.
2
(0.6 G) (10 to 55 Hz) or less. (0.4 to 22kW)
2
2.94 m/s
(0.3 G) (10 to 55Hz) or less. (30 to 150kW)
