Precautions for EMC, Models SJ700-1850 to -4000
The SJ700
2
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.
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 requirements
a.
A special filter and a ferrite core intended for the SJ700
2
large capacity series inverter
must be installed, shown in the table below.
b.
A provided direct reactor with the SJ700 large capacity series inverter must be installed.
