The voltage and connection method is noted on the motor nameplate. But, as a general
rule, larger motors (380/660V) are delta-connected and smaller motors (220/380V) are
star-connected.

Use only screened cable for the control cable.
To access the control terminals on the SED1 frame sizes B and C, open the terminal
cover (see section 3.2.3.2).
On the SED1 frame sizes 4 to 7, remove the front cover (on frame size 7, only remove
the lower cover).
On frame sizes 4 to 7, the terminal blocks are of a two-part design. The part containing
the screw terminals is unplugged from its housing before any wires are connected.
When all connections to the terminals have been secured, firmly replug the terminal
block into its housing.
