Figure 8.6 Input-Side Noise Filter (Three-Phase 200/400 V)
This drive is tested according to European standards IEC61800-5-1 and complies with the EMC guidelines. Refer to
EMC Filter Installation on page 411
for details about EMC filter selection and installation.

Output-Side Noise Filter
A noise filter on the output side of the drive reduces inductive noise and radiated noise.
illustrates an example
of output-side noise filter wiring.
NOTICE:
Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Improper application of noise filters
could result in damage to the drive.

Fuses
To protect the drive and avoid damage from a short-circuit, a fuse should be installed to the input side of the drive.
Refer to European Standards on page 410
and
Refer to UL Standards on page 416
for details on input fuse installation.

External Heatsink Attachment
An external heatsink attachment makes it possible to place the heatsink used to cool the drive and components outside
the enclosure panel. It may still be necessary to allow for airflow around the drive case.
Contact your Yaskawa representative or Yaskawa directly for questions on the external heatsink attachment.
