Class T:
The T-class converters have a smaller earth leakage current and are intended to be used with IT supplies
only. If they are used with other supplies no EMC requirements are complied with.
Class N:
The drives of this class do not provide EMC emission protection. This kind of drives are mounted in
enclosures. External EMC filtering is usually required to fulfil the EMC emission requirements.
All Vacon NX frequency converters fulfil all EMC immunity requirements (standards EN 61000-6-1,
EN 61000-6-2 and EN 61800-3+A11).
Note: For changing the EMC protection class of your Vacon NX frequency converter from class H or L to
class T, please refer to the instructions given in Chapter 6.1.3.
