If the voltage has to be changed from 415V three-phase to 240V three-phase (Fig.4), proceed 
as follows: 
1.  The 415V 50Hz three-phase motor has two groups of cables each containing three leads of 

three different colours. 

2.  The three wires with different colours are short-circuited and separated under a cover or 

terminal. 

3.  The other three leads are directly connected to the interface card. 
4.  To make the connection for 240V three-phase, separate the three leads that are joined. 
5.  Combine three pairs of leads of the same colour and then recreate the connection of the 

leads matched in this way to the terminals of the card marked with the codes U -V -W. 

6.  Finally, make the new connection of the lead in the bridge position between references 0-

415, moving one end to coincide with the new value (240). 

After completing the connections run a test and check for correct direction of rotation of the 
motor.
