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.

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.
