When the external wire enters the interior of the unit through a waterproof cable connector, you need to separate the
strong-current cable from the weak-current cable for cabling. For details, see the diagram.
Inside the unit, wires should be fixed by using a cable tie through the overpass-shape component.
The signal cables X1/X2 and P/Q/E must be fitted with a magnetic ring, and then all cables fixed on the overpass-shaped
component by using a cable tie.

Used for energy management and to identify free valley.
When N1 is connected to N2, the electricity is
determined to be free electricity. When M1 is connected
to M2, the electricity is determined to be cheap
electricity. When receiving cheap or free electrical signal,
the hydro module will automatically start. (For detailed
settings, refer to the User Manual.)
