Multiple Load Connection with Distribution Terminals
3.9.10
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 Figure 3-13).
If remote sensing is required, the sensing wires should be connected to the distribution terminals or at the most
critical load.

Grounding Outputs
3.9.11
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.
