mainly tests the conduction interference rejection, radiation interference rejection,
surge interference rejection, fast and mutable pluses group interference rejection,
ESD interference rejection and power low frequency end interference rejection
(specific test items including: 1. Interference rejection tests of input voltage sag,
interrupt and change; 2. Phase conversion interference rejection test; 3. Harmonic
input interference rejection test; 4. Input frequency change test; 5. Input voltage
unbalance test; 6. input voltage fluctuation test).
In accordance with the above requirements of IEC/EN61800-3 to be tested ,our
products are installed and used according to Section 6.3 and have a good
electromagnetic compatibility in general industry environment
6.3 EMC Guide
6.3.1 Harmonic Effect
Higher harmonics of power supply may damage the inverter .Thus ,at some
places where mains quality is rather poor ,it is recommended to install AC input
reactor.
6.3.2 Precautions on Electromagnetic Interference and Installation
There are two kinds of electromagnetic interference .one is interference of
electromagnetic noise in the surrounding environment on the inverter, and the other
is interference of inverter on the surrounding equipment.
installation precautions:
