To reduce the degree of output overshoot which can result from accidentally opened remote sensing
connections, many regulated power supplies include internally wired resistors or small silicon diodes as shown
in Figures 50 and 51. If they are not part of the power supply, and if the power supply application involves long
sensing leads, sensing paths which include relay, switch, or connector contacts, or any other likely cause of
even momentary open-circuits in the remote sensing paths; then the user should add either resistors or silicon
diodes.

If the diode configuration of Figure 51 is employed, operation will be satisfactory up to about 0.5 volts drop in
either load lead (between a power supply output terminal and the corresponding DC Distribution Terminal); for
greater drops use two or more diodes in series.
