Connections-Single Unit
Route the load leads through the safety cover before attaching the safety cover to the rear panel. The following figures
illustrate the two types of safety covers installed.
Large safety cover - for all models Small safety cover - for models rated 500 V and up
Units units rated 500 V and up use both safety covers
Knockouts are provided on the large safety cover so that the load wires can be run in various directions. Note that
heavy load cables must have some form of strain relief to prevent bending the safety cover or bus-bars.
Always twist or bundle the load wires to reduce lead inductance and noise pickup. The goal is to always minimize the
loop area or physical space between the + and - load wires from the power supply to the load.
Multiple Load Connections
If you are using local sensing and are connecting multiple loads to one output, connect each load to the output ter-
minals using separate load wires as shown in the following figure. This minimizes mutual coupling effects and takes full
advantage of the power supply's low output impedance. Keep each wire-pair as short as possible and twist or bundle the
wires to reduce lead inductance and noise pickup. The goal is to always minimize the loop area or physical space
between the + and - load wires from the power supply to the load.
If load considerations require the use of distribution terminals that are located away from the power supply, twist or
bundle the wires from the output terminals to the remote distribution terminals. Connect each load to the distribution
terminals separately. Remote voltage sensing is recommended under these circumstances. Sense either at the remote
distribution terminals or, if one load is more sensitive than the others, directly at the critical load.
