3.9.9 Connecting multiple loads, radial distribution method
Fig.3-12 shows multiple loads connected to one supply. Each load should be connected to the
power supply’s output terminals using separate pairs of wires. It is recommended that each pair of
wires will be as short as possible and twisted or shielded to minimize noise pick-up and radiation.
The sense wires should be connected to the power supply output terminals or to the load with the
most critical load regulation requirement.

3.9.10 Multiple load connection with distribution terminals
If remotely located output distribution terminals are used, the power supply output terminals should
be connected to the distribution terminals by a pair of twisted and/or shielded wires. Each load
should be separately connected to the remote distribution terminals (see Fig.3-13). If remote
sensing is required, the sensing wires should be connected to the distribution terminals or at the
most critical load.

3.9.11 Grounding outputs
Either the positive or negative output terminals can be grounded. To avoid noise problems caused
by common-mode current flowing from the load to ground, it is recommended to ground the output
terminal as close as possible to the power supply chassis ground. Always use two wires to connect
the load to the power supply regardless of how the system is grounded.
WARNING
Models up to 60VDC Rated Output shall not float outputs more than
+/-60VDC above/below chassis ground. Models > 60VDC Rated Output
shall not float outputs more than +/-600VDC above/below chassis ground.
