• 3 phases with 1 zero connection (3 1N, 400 V ~ / 50 Hz):

º The voltage between the phase and the zero is 230 V ~.

The voltage between the two phases is 400 V ~.

Fit a connecting bridge between connecting points 4-4. Phase

3 carries no load. The groups must have fuses of at least 16 A

(3x). The core diameter of the connecting cable must be at least

2.5 mm

• 2 phases with 1 zero connection (2 1N, 400 V ~ / 50 Hz):

º The voltage between the phase and the zero is 230 V ~.

The voltage between the two phases is 400 V ~. If there is not

a voltage of 400 V ~ between the phases, two wires have

been taken from the same phase in the meter cupboard

and the hob must be connected with two neutral wires, as

indicated under 2 phases with 2 neutrals. Fit a connecting

bridge between connecting points 3-4. The groups must have

fuses of at least 16 A (2x). The core diameter of the connecting
