3-2-6. Series operation: When using constant voltage output mode
Connect the CV terminals in a daisy chain and apply an external voltage to the CV terminals.
Connect between the CV terminals (pin No. 16 of CN41 or CN42) and the AG terminals (pin No. 11 or pin
No. 12 of CN41 or CN42) of all power supplies operating in parallel. Apply an external voltage between the
CV and AG terminals.
The wires between CV 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.
