Reference to the preparation of aluminum conductors:
Clean the bared conductor end carefully by scraping off the oxide film, for example with a knife, (Please do not use rasps, emery paper or brushes!).
Immediately after removing the oxide film the conductor end is to rub in with acid and alkali free fat for example vaseline, and immediately to be connected in the terminal.
The prementioned processing steps are to be repeated, if the conductor was disconnected and connected again.
Due to the disposition to flowing of aluminum the terminals are to be re-tightened before start-up and after the first 200 operation hours.
