External Series Connections. To achieve a potential across the load
that exceeds the output of a single power supply, connect two or
more power supplies in series. Figure 8 illustrates two independent
power supplies connected in series. Note that the voltages of the
power supplies add together but the currents do not.

WARNING. Voltages more than 60 VDC are a lethal shock hazard to
the user. Be careful when connecting power supplies in series to
achieve voltages higher than 60 VDC total or 60 VDC between any
connection and earth ground.
Refer to Figure 9 for examples of different types of series connec-
tions using the three outputs.
