
The supply voltage of the E.BOX PLUS panel must be the same as that of the pumps used. For
example, if the panel is fed with a supply voltage of 3~400V the pumps must be at 3~400V.

The E.BOX BASIC panel must be fed with a supply voltage of 1~230V. The pumps must be single-
phase 230V.

Connect the earth cables of the pumps to the earth terminals in the E.Box panel! Make sure that all
the cables have adequate dimensions for the currents they have to bear.

If the single-phase pump needs an external capacitor, it can be placed inside the panel.

If 2 pumps are used, they must be identical.

Attention, an incorrect electrical connection could damage the E.Box panel.

2.2 Electrical connection of the pumps

Connection of three-phase pumps

Three-phase pumps can be connected only to the E.box Plus. They must be connected to the terminals P1
and P2 as shown in Figure 3. The correct sequence of phases U, V and W must be respected so that they
turn in the correct direction.

Connection of single-phase pumps with internal capacitor.

The pumps must be connected to the terminals P1 and P2 shown in Figure 3. The neutral wire must be connected to
the terminal N, the phase wire must be connected to the terminal with a screenprinted L.

Connection of single-phase pumps with external capacitor.

Pumps with an external capacitor must be connected to the terminals P1 and P2 shown in Figure 5. Particular care
must be taken to respect the correspondence between the screenprinting and the names of the pump wires. The
pump cable marked C must be connected to terminal C. The same applies to cables A and P. See Figure 3.
The pump capacitor can be placed inside the E.box panel, on the metal bracket provided.
