WARNING!
If connecting external piping to the internal cooling circuit, use only materials
that are specified above. Copper, brass or bronze must not be used under
any circumstances. Even minor dissolution of copper can cause copper
precipitation on aluminum and subsequent galvanic corrosion. The liquid
cooling system must not contain any zinc (eg. galvanized pipes).
If the plant incorporates normal iron pipes or cast iron accessories (eg. motor housings), a
cooling unit with a heat exchanger (such as the ACS880-1007LC) must be used to separate
the systems.
