When you first install EasyPower, you are given the option to set your base symbols to ANSI or IEC. If you want to change this later, you can do so by selecting the appropriate standard in Tools > Options > One-line Symbols.
After you change the symbols, you must close and re-open EasyPower to see the changes in the program.
