7.2 Power supply
7.2.1 Single-phase supply voltage
• 1 x 200-240 V - 10 %/+ 10 %, 50/60 Hz, PE.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
The wires in the motor terminal box must be as short as possible.
Excepted from this is the separated ground conductor which must
be so long that it is the last one to be disconnected in case the
cable is inadvertently pulled out of the cable entry.
For maximum backup fuse, see section 17.1 Supply voltage.

7.2.2 Three-phase supply voltage
• 3 x 440-480 V - 10 %/+ 10 %, 50/60 Hz, PE.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
The wires in the motor terminal box must be as short as possible.
Excepted from this is the separated ground conductor which must
be so long that it is the last one to be disconnected in case the
cable is inadvertently pulled out of the cable entry.
For maximum backup fuse, see section 18.1 Supply voltage.

In order to avoid loose connections, ensure that
the terminal block for L1, L2 and L3 is pressed
home in its socket when the supply cable has
been connected.
Corner grounding is not allowed for supply
voltages above 3 x 480 V, 50/60 Hz.
