INSTALLATION INSTRUCTIONS
electrical connection
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
.
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.
Fit a connecting bridge between connecting points1 and 2. 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

.
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 2 and 2, 2 and 3,
and 4 and 5. The group must have a fuse of at least 40 A. The
core diameter of the connecting should be at least 6 mm
2
.
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, and 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
