connected in triangle when the three phased line tension is 230V, as it is indicated below:
Star picture Picture triangle
Likewise it is necessaryto change the input transformer terminals for the change of tension. Input 400 V.
(Terminals “0”and “400”). Input 230 V. (Terminals “0” and “230”).
This modification must be carried out in the connector to the electric card.

be replaced by one with three phase 230V input.
It is very important to connect properly tha machine to the ground socket.
