Changing EMC protection class from H to T
The EMC protection class of Vacon NXL frequency converter types MF4 – MF6 can be changed from
class H to class T with a simple procedure presented in the figures below.

Note! Do not attempt to change the EMC-level back to class H. Even if the procedure above is
reversed, the frequency converter will no longer fulfil the EMC requirements of class H!
