Configuring Multiple Supplies for Split Supply Operation

Split supply operating uses two power supplies to obtain two positive voltages with
a common ground, or to obtain a positive-negative supply.
Two Positive Voltages To obtain two positive voltages, connect the negative
output terminals of both supplies together in a common connection. The positive
output terminals will provide the required voltages with respect to the common
connection.
