Figure 11.4 Installing the Inverter with EMC-compliant Filter into a Metal Panel
Note 1
: Pass the EMC filter input wires through the ferrite ring reactor for reducing radio noise
(ACL-40B) two times.
Note 2
: Pass the EMC filter output wires (shielded cable and grounding wire in a bundle) through
the ferrite ring reactor for reducing radio noise (ACL-40B) two times.
Note 3
: Connect the shielding layer of the shielded cable to the motor and panel electrically and
ground the motor and panel.
Radiated noise varies greatly depending upon the installation environment. When no
ferrite ring reactor is used, make sure that the radiated noise does not exceed the
permissible level.
