INSTRUCTIONS AND DIAGRAMS FOR THE REPLACEMENT OF THE CODE 240 CARD WITH THE CODE 390S
CARD
When installing the code 390S in the place of the code 240, the tachometric inversion contact is eliminated. The rest
of the terminal board numbered from 1 to 8 is perfectly compatible and the connections do not need to be moved as
shown by the circled numbers in the diagram below.
Follow the same indication for the power connections.
The supply line (W1-V1-U1 code 240) is moved to terminals R1-S1-T1 of the code 390, and the motor outputs (V2-U2-
W2 code 240) should be moved to terminals U1-V1-W1 of the code 390. The 3 wires (U1-V1-W1) of the code 240 that
first went to the motors should be removed and the motor should be delta connected.
If terminal 8 for motor couple limitation on card 240 is connected, close the S9 micro on card 390S.
Set the micros on the code 390S card as follows:
S1 – S5 – S6 – S8 – S10 – S11 – S12 Closed
S4 – S7 – S9 Open
S2 – S3 see instructions
