Electrical connection
Common connections:
• 3 phase and 1 zero connection (3 1N, 400 V~/ 50 Hz):
▷ The voltage between the phases and the neutral is 230 V~. The
voltage between the two phases is 400 V~. Fit a connecting
bridge between connecting points 4-5. 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 phase and 2 neutral connection (2 2N, 230 V~ / 50 Hz):
▷ The voltage between the phases and the neutral 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
