WARNING

Ground wires must be connected to the piping and any other peripheral equipment. When operating the
pump make sure it is properly grounded. Otherwise friction between the parts and abrasion caused by
some fluids flowing inside the casing may generate static electricity. In addition it may cause fire or electric
shock, depending on the type of fluid being pumped and the installation environment (such as gases in the
air or the surrounding mixtures).

Only appropriately educated professional personnel may carry out with any electric works!

Keep the terminal plan in the distribution cabinet!
