3.3.2 Emission and Immunity
Levels Description
EMC Phenomenon
Emission:
Conducted Emission (Mains Terminal
Disturbance Voltage - Frequency Band
150 kHz to 30 MHz)
Radiated Emission (Electromagnetic
Radiation Disturbance - Frequency
Band 30 MHz to 1000 MHz)
Immunity:
Electrostatic Discharge (ESD)
Fast Transient-burst
Conducted Radio-frequency
Common Mode
Surge
Radio-frequency Electromagnetic Field
CHAPTER 3 - INSTALLATION AND CONNECTION
4) The length of the wiring between filter and inverter must be
kept as short as possible.
5) The cables shielding (motor and control) must be solidly
connected to the common back plate, using a metal bracket.
6) Grounding as recommended in this manual.
7) Use short earthing cable to earth the external filter or inverter.
When an external filter is used, only use an earth cable at
filter input - the inverter earth connection is done by the metallic
back plate.
8) Earth the back plate using a braid, as short as possible. Flat
conductors (e.g. braids or brackets) have lower impedance
at high frequencies.
9) Use cable glands whenever possible.
