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.3-9).
If remote sensing is required, the sensing wires should be connected to the distribution terminals
or at the most critical load.
Load lines, twisted pair, shortest length possible.

3.9.9 Connecting Multiple Loads, Radial Distribution Method
Fig.3-8 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.
