9 Beeps (3 short, 3 longer, 3 short)

During the clean install of macOS High Sierra on my iMac11,3 (27-inch, medio 2010) it keeps restarting with 9 Beeps (3 short, 3 longer, 3 short)

I hope someone knows how to solve this

see > About Mac startup tones - Apple Support

If you disturbed the ROM Recovery or it does not recover on it own as stated in the article, then you will need to contact Apple Support or make an appointment at your local Apple Store or AASP.
