Electrical connection
Common connections:
• 2 phase and 1 zero connection (2 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. The groups must have
fuses of at least 16 A (2x). The core diameter of the connecting
cable must be at least 2.5 mm
