5.4 Multiple loads 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 or shielded wires. Each load should be separately connected to the remote distribution terminals (see Fig 5-4). If remote sensing is required, the sensing wires should be connected to the distribution terminals or at the most critical load.

5.5 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's output. Always use two wires to connect the load to the power supply regardless of how the system is grounded.
