WARNING

Exercise caution when operating the power supply. High energy levels can be stored at the output terminals on a power supply in normal operation. In addition, potentially lethal voltages exist in the power circuit and on the output and sense connectors of a power supply with a rated output greater than 40V. Filter capacitors store potentially dangerous energy for some time after power is removed.

CAUTION

When making connections to the bus bars, ensure that each terminal’s mounting hardware and wiring assembly are placed to avoid touching the other terminal and shorting the power supply outlet. Heavy connecting cables must have some form of strain relief so they don’t loosen the connections or bend the bus bars.

Make load connections at the rear of the power supply at the positive and negative output bus bars or to the 4-terminal wire clamp connector, depending on the model. (See Figure 2.7.)

Wire Size The wire should be one size larger than necessary to accommodate the required output current. Normally, the next largest commonly used gauge is used. For example, use 10AWG for 20A, and 8AWG for 30A.

Isolation The wire must have a suitable insulating coating that will prevent arcing between the positive and negative output current, and must be rated for 105°C operation.
