The maximum current of transformers/reactors is dependent on the ambient
temperature and the installation altitude. The permissible current/power rating of
the transformers and reactors is:

Note: The secondary voltage increases and the NE modules should be set to S1.1=ON, refer to Section 6.1.
2) Assigning isolating transformers to I/R modules, refer to Catalog NC 60.
