INSTRUCTIONS AND DIAGRAMS FOR THE REPLACEMENT OF THE CODES 290 AND 290R CARDS WITH THE
CODE 390S CARD
To correctly replace the codes 290 and 290R cards with the 390S type card, follow the circled numbers shown in the
diagrams below. As can be seen, the cards are interchangeable even if the terminal boards are dislocated. The terminals
R1 S1 T1 and U1 V1 W1 are common to both power terminal boards, as is the numbering of the service terminal board
up to number 11.
If terminal 11 (motor current adjustment) is connected in the replacement 390S card, it is necessary to connect the
amperometric transformer to terminals 7 – 15, open micro S8, close micro S9 and follow the instructions given on page
14 regarding connection diagram nr. 2.
In both cases, set the micros on the code 390S card as follows:
S5 – S6 – S8 – S10 – S11 – S12 Closed
S1 – S4 – S7 – S9
Open
S2 – S3 See instructions
