Load Connection
TM-F1OP-C1XN-01 2-15
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 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.
Making Load Connections
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.
WARNING: Shock hazard
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 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.
