service personnel in the correct behaviors while handling the pumping station. He ex-
plains that damages to persons and systems can occur, if the pumping station is not
operated correctly. To this in particular belong also information concerning the residual
risks.
• Before maintenance and repairs the pumping station is shut down. The main switch,
