3-1-5. Series parallel connection
When using series-parallel connections, connect the series-connected power supplies in parallel.
If power supplies connected in parallel are connected in series, the output may become unstable.
Use load wires from each series-connected power supply that are the same size and length.
Connect between the VB terminals (pin No. 14 of CN41 or CN42) and the AG terminals (pin No. 11 or
pin No. 12 of CN41 or CN42) of the power supplies connected in series.
Connect between the CB terminals (pin No. 13 of CN41 or CN42) and the AG terminals (pin No. 11 or
pin No. 12 of CN41 or CN42) of all power supplies.
The wires between the VB, CB, and AG terminals should be the same length and as short as possible,
and twisted or shielded wires should be used.
To protect when one unit stops, connect the HL terminals (CN41 or CN42 pin No. 7) and the DG
terminals (CN41 or CN42 pin No. 4 or pin No. 6) of all power supplies.
The wires between HL terminals and DG terminals should be the same length and as short as possible, and twisted or
shielded wires should be used.
