Common connection:
3 phases with 1 zero connection (3 1N a.c. 400V/50 Hz):
The voltage between the phases and the zero is 230V a.c. The
voltage between the two phases is 400V. Fit a connecting bridge
between connecting points 4 and 5. 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 zero connection (2 2N a.c. 230V/50 Hz):
The voltage between the phases and the zeros is 230V a.c.
The group must have fuses of at least 16 A (2x) The core dia-
meter of the connecting cable must be at least 2.5 mm

Special connections:
Single phase connection (1 1N a.c. 230V/50 Hz):
The voltage between the phase and the zero is 230V a.c. Fit a
connecting bridge between connecting points 1 and 2, and
4 and 5. The group must have a fuse of at least 32 A. The core
diameter of the connecting should be at least 6 mm

.
3 phase, no zero connection (3 a.c. 230V/50 Hz):
The voltage between the phases is 230V a.c. Fit connecting
bridges between connecting points 1 and 2, 4 and 5. The group
must have fuses of at least 16 A (3x). The core diameter of the
connecting cable must be at least 2.5 mm
