3.9.7 Connecting single loads, local sensing (default).
Fig.3-10 shows recommended load and sensing connections for a sing le load. The local sense
lines shown are def ault connections at the rear panel J2 sense connector. Local sensing is suit-
able for applications where load regulation is less critical.

3.9.8 Connecting single loads, remote sensing
Fig.3-11 shows recommended remote sensing connect ion for single loads. Remote sensing is
used when, in Constant Voltage mode, the load regulation is important at the load terminals. Use
twisted or shielded wires to minimize noise pick -up. If shielded wires are used, the shield should
be connected to the ground at one point, either at the power supply chassis or the load ground.
The optimal point for the shield ground should be determined by experimentation.

3.9.9 Connecting multiple loads, radial distribution method
Fig.3-12 shows multiple loads connected to one supply. Each load should be connected to t he
power supply’s output terminals using separate airs 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.
