Making Load
Connections
Make load connections to the power supply at output connectors at the rear of the
power supply, or at the binding posts on the front panel.
Binding Posts (All Models) The binding posts on the front panel have a built-in
current limiting function which will not allow more than 30 A to be drawn from the
output on units with high output current capability. If the draw exceeds 30 A, the
Binding Post Overload (OL) LED on the front panel lights up and the current draw
is limited to 30 A. Once the load draw drops below 30 A, the OL LED goes out and
normal operation resumes. Use remote sensing to improve load regulation at the
binding posts. See
“Specifications” on page 23 for any differences in specifications
when operating with the load connected at the binding posts.
7.5 V to 40 V Models
The 7.5 V to 40 V models have output bus bars on the rear panel and come with a
bus bar shield. A filter capacitor and the A16 EMI filter board are attached to the bus
bars on the rear panel. Detach only the bus bar shield before making load or remote
sense line connections. To detach the shield, remove the screws as shown in
Figure 2.3.
WARNING
There is a potential 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
Do not remove the A16 EMI filter board or the bus bar capacitor from the bus
bars. Operating the power supply without the EMI filter board or the bus bar
capacitor will impair its electrical performance.
!
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.
