7.2 External EMC Filter
Additional external EMC filters are sometimes required to meet specific conducted emissions standards
and environments.
All products have internal filters that meet the Category C3 limits defined in EN61800-3. Where this
performance is not adequate for a customer’s application, the Conducted Emissions plots provided in
‘Chapter 11: Compliance’ allow for the selection or design of an additional external EMC filter to meet
customer’s needs.
EMC advice to consider during the product installation can also be found in this section.
7.3 AC Line Choke
An External AC Line Choke may be required on the line supply to the drive:
1. On supplies delivering >12kA but <50kA RMS symmetrical Amperes, 480V maximum.
2. To mitigate supply quality issues.
Where required, Parker suggest the following AC Line Choke ratings:

Notes:
- AC Line Choke inductance values calculated @230V, 50Hz
- AC Line Choke impedance is nominally 3% of drive rating
- AC Line Choke maximum voltage rating should be 240V +10%, TN/IT
- AC Line Choke frequency of operation is 50 – 60Hz
- AC Line Choke inductance during 150% overload operation should be >90% of its nominal value
