CONNECTING THE MOTOR
Check the specifications of the motor and compare
them with the voltage available on your installation
before making connections. Connect up the motor in
accordance with the instructions in the terminal box
(Fig. 2.5a).
A delta connection is required to connect up
to a 230 V 3-phase power supply (Fig. 2.5b).
A star connection is required to connect up to
a 400 V 3-phase power supply (Fig. 2.5c).
For connection in SINGLE-PHASE mode,
see Figure 2.5d.
Replace the existing wires with those of your electrical
power supply.
CAUTION : Do not forget to connect the earth terminal
on the motor [PE] (Fig. 2.5a) to the equipment earth
conductor.
The electrical protection installed for the motor (fuse or
thermal protection) must be suitable for the motor's
rated current.
