When you perform a component cross reference
you may get an Error/Exception Report advising that you have “Too many NO contacts”
Whilst there may be a valid error, there is also the chance that the report may be misleading because there is an unnecessary attribute in a few symbols in the IEC* libraries.
The following symbols in the IEC2, IEC4 and IEC-60617 have the additional and unrequired attribute of CONTACT with a value of NO. You can open these symbols up (File > Open) and remove the value and/or the CONTACT attribute to rectify.

If you have already placed the symbol in your schematic, it can be easily updated using the Swap / Update Blocks command.
