Refer to the following figure for typical connections of series power
supplies configured as a positive and a negative output.
CAUTION
This caution applies when using analog voltage programming with series-
connected power supplies. The analog programming circuits of these power
supplies are referenced to the negative sense (-S) potential. Therefore, the
analog voltage circuits used to control each series-connected unit must be
separated and floated from each other.
