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.
!
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.
6 V to 40 V Models The 6 V to 40 V (low voltage) models have output bus bars
and may come with a bus bar shield in some configurations. To detach the shield
before connecting load wires, remove 6-32 x 1/4 in. screws (2), 6-32 x 3/8 in. screw
(1), and lock washers and flat washers (3 places). See Figure 2.4.

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.
