Connecting the Outputs
After setting the voltage and current limits, turn the power off and
connect the outputs to one or more loads. The binding posts on the
front outputs accept wires, spade lugs, or banana plugs. The rear
output terminals provide additional output connections. You can
make connections with or without reference to ground to each supply
independently, in series or in parallel.
WARNING.
To avoid electrical shock and damage to circuits
connected to the outputs, make sure that you turn the power supply
off before making or changing output connections.
Referencing Outputs to Ground
There are two types of power supply connections in relation to
ground: isolated ground or ground referenced. Figure 6 shows both
types of connections.

Figure 6: Isolated-Ground Connection
Use an isolated-ground connection when it is unnecessary or
undesirable to connect one of the outputs to ground.
To reference an output connection to ground, do one of the
following:
H
Connect the positive output to the ground terminal to supply a
negative voltage across the load.
