INSTALLATION
Common connections:
• 2 phase and 2 zero connection (2L 2N, 230 V ~ / 50 Hz):
▷ The voltage between the phases and the zeros is 230 V ~.
The group must have fuses of at least 16 A (2x). The core
diameter of the connecting cable must be at least 2.5 mm

• 3 phases with 1 zero connection (3L 1N, 400 V ~ / 50 Hz):
▷ 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 3-4. Phase 3 carries no load.

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