Noise and Impedance Effects To minimize noise pickup or radiation, use shielded pair wiring of shortest possible length for load wires. Connect the shield to the power supply chassis. Where shielding is impossible or impractical, simply twisting the wires together will offer some noise immunity.

Making Load

Connections

WARNING

There is a shock hazard at the load when using a power supply with a rated output greater than 40 V. To protect personnel against accidental contact with hazardous voltages, ensure that the load, including connections, has no live parts which are accessible. Also ensure that the insulation rating of the load wiring and circuitry is greater than or equal to the maximum output voltage of the power supply.

CAUTION

When making connections to the bus bars, ensure that each terminals’ 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.
