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.

Electrical connection of the 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.

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.

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.
