3-1-6. Redundant operation disable function
When linking multiple power supplies, it is possible to disable redundant operation so that all units stop 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 to be linked.
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.
3-1-7. Auxiliary power supply
Connect the AUX terminal (pin No. 1 and pin No. 2) and GND terminal (pin No. 3 and pin No. 4) of
CN71 to the external load.
Twist the load wires.
