Multiple Loads
If you are using the
If load considerations require the use of distribution terminals that are located remotely from the supply, connect the power supply output terminals to the remote distribution terminals by a pair of twisted or bundled wires. 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.

Positive and Negative Voltages
Either positive or negative voltages can be obtained from the supply by grounding (or "commoning") one of the output terminals. Always use two wires to connect the load to the supply regardless of where or how the system is grounded.
This supply can be operated with any output terminal ±240 Vdc (including output voltage) from ground.
Remote Voltage Sensing
Because of the unavoidable voltage drop developed in the load leads, the
