Hydro-Pro HYDRO PRO5 Bedienungsanleitung Seite 18

Note: In the case of three-phase models, swapping two phases may cause the electric motors
to run in the reverse direction, which can lead to damage. For this reason, the unit has a
built-in protective device that breaks the circuit if the connection is not correct. If the red LED
above this safety device lights up, you must swap the connections of two of the phase
wires.
