Noise and
Impedance
Effects
To minimize noise pickup or radiation, use shielded-twisted pair wiring of as short a
length as possible 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 the
Connections
Make load connections to the power supply at the positive and negative output
terminals (or bus bars) at the rear of the power supply. See
Figure 1.2, “Power
Supply Rear Panel” on page 20
. The power supply provides three load wiring
mounting holes on each bus bar terminal as specified in the following table.
Connecting
Single Loads
Figure 2.5
and
Figure 2.6
show recommended load and sensing connections for
single loads. Local sense lines shown are default J3 connections. Refer to
“Connecting Remote Sensing Lines” on page 44
for more information about the
sense line shield.
!
CAUTION
When making connections to the bus bars, ensure each terminal's mounting
hardware and wiring assembly is 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.
