Connecting Single Loads
Figure 7 shows the recommended load connections for a single load which is sensing its
voltage locally. Local sense lines shown are the default connections at the rear panel APG J1
connector. The load lines should use the largest gauge and shortest length of wire possible to
ensure optimal performance.
You do not need remote sensing for basic operation of your power supply. However, if you
wish to correct any small drops in your load lines, then use the remote sensing feature. See
“Step

Connecting Remote Sensing” on page 28for more information.

Connecting Multiple Loads
The proper connection of distributed loads is an important aspect of power supply use. The
common method of connection is a radial load connection. Power is connected to each load
individually from a single pair of terminals designated as the positive and negative
distribution terminals. This pair of terminals may be the power supply output terminals, the
load terminals, or a distinct set of terminals especially established for distribution use. In this
scheme, there are no ground loops and the effect of one load upon another is minimized.
