Installation Notes
- If a controller or robot connection will be used, allow the software through the Windows firewall when prompted.
- After installation, re-enable antivirus protection and add the program folder to the allowed list if your policy requires it.
- Reboot the PC once after installation completes — this finalizes driver and service registration.
- Run the installer as administrator and keep the default path unless your company standard requires otherwise.
- Launch the application once with administrator rights so it can register its components before first normal use.
Frequently Asked Questions
Can I import from other ECAD tools?
Yes, common exchange formats are supported; expect some manual cleanup of symbols and device data on first import.
Is multi-user editing possible?
Projects can split into page-based work for parallel editing; coordinate access with your team.
How are revisions handled?
Revision control tracks changes per page and device, so updates stay traceable.
Does it generate manufacturing documents?
BOM, cable lists, terminal plans and panel layouts are generated directly from the schematics.

Tips from Real Projects
On a skid-build project, ETAP 21 page macros let the electrical team keep pace with mechanical changes arriving weekly. The habits that carried it: device data pulled from one parts database, revision discipline enforced per page, and wire numbers generated — never typed. Lock macro versions per project — a mid-build library update rippling through released pages is a weekend nobody gets back.
