Noise and Impedance Effects
To minimize noise pickup or radiation, use shielded-twisted pair wiring of the shortest possible length for load
wires. Connect the shield to the chassis via a rear panel mounting screw. Where shielding is impossible or
impractical, simply twisting the wires together will offer some noise immunity. When using local sense
connections, use the largest practical wire size to minimize the effects of load line impedance on the regulation
of the supply.
2.7.2 Making Load Connections
WARNING
There is a shock hazard at the load when using a power supply with a rated
output greater than 40V. Install a physical shield for the connections at any
load attached to a power supply with a rated output greater than 40V.
CAUTION
When making connections to the bus bars, ensure each terminal's mounting
hardware and wiring assembly are placed to avoid touching the other
terminal and shorting the power supply output. Heavy connecting cables
must have some form of strain relief to avoid loosening the connections or
bending 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.
