Changing EMC protection class from H/C to T in NXL HVAC
The EMC protection class of NXL HVAC frequency converter types can be changed from class H/C
to class T with a simple procedure presented in the figures below.
Figure 5-7. Changing of EMC protection class, MF4 (left) and MF5 (right)

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