Connecting Single Loads, Local Sensing (default configuration).
Figure 3-10 shows recommended load and sensing connections for a single load. The local sense lines shown
are default connections at the rear panel J2 sense connector. Local sensing is suitable for applications where
load regulation is less critical.

Connecting Single Loads, Remote Sensing
Figure 3-11 shows recommended remote sensing connection 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
Figure.3-12 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.
