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.
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.
Load lines, twisted pair,
shortest length possible.
