I started with one of the supplied IEC templates and I modified it to have X zones, numbered 1 through 8. There is a sample IEC project available from my web site. It’s just that the symbols from the IEC2 and IEC4 libraries use the legacy component identification lettering scheme. All three libraries use symbol graphics from IEC-60617. The symbols from the IEC-60617 library use the two-letter identification, from IEC81346-2. In the Libs folder, you will see folders, IEC2 (2mm text height), IEC4 (4mm text height), and IEC-60617 (4mm text height). Most of us make a custom drawing template, with our company name, logo, etc. (see screenshot) Be sure to add the numbers across the top of the drawing template, if you make a custom template.

You can define whether to number the zones as 0 through 9, 1 through 8, etc. IEC will need ladder orientation set to horizontal, with an X zones. Look at Project Properties for the library assignment, tagging formats, cross-reference style, PLC style, etc. Use the IECdemo project as a project template. We can choose to use them or not, but the content is there. To streamline the installation process, since many of us use multiple standards, Autodesk no longer makes us pick through the content options.

I have designed to both standards since 1991, but most of my work is still IEC. Later I had to start designing to American standards as well. I started designing to DIN standards, later IEC, in 1988, while working for a German manufacturer. That's been my life, both ways, for decades. Europeans are designing to NFPA standards, so they can sell their products to American customers, and Americans are designing to IEC standards, so they can sell their products to Europe. Most of us are designing to multiple standards these days. AutoCAD Electrical 20 installs all content.
