The Remote Analog programming circuits of this Power Supply
are referenced to the negative local sense (-LS) potential.
Therefore, the circuits used to control each series connected unit
must be separated and floated from each other using the
Isolated Analog interface option.
The Shut-Off and PS_OK circuits are referenced to the isolated
interface common, IF_COM (J1-2,-3). The IF_COM terminals of
different units can be connected together to obtain a single
control circuit for the power supplies connected in series.
See Section 6.5.1 for details.
Programming by external resistor is possible.
Refer to Section 7.5 for details.
The communication port is referenced to the isolated interface
common, IF_COM (J1-2, -3), which is isolated from the Power
Supply output potential. Therefore, power supplies connected in
series can be daisy-chained using the Remote-In and Remote-
Out connectors. Refer to Chapter 8 for details.
