Connecting Multiple Loads, Radial Distribution Method

Figure 2–3 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.

2.2.4

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 Figure 2–4).
If remote sensing is required, the sensing wires should be connected to the distribution terminals or
at the most critical load.
In remote sense, the power supply will compensate for voltage drop on the load wires. Refer to the
Specifications in the Safety and Installation Manual for the maximum voltage drop on load wires.
The voltage drop is subtracted from the total voltage available at the output.
