Multiple load c
onnection with distribution terminals
If remotely located output distribution terminals are used, the power supply output terminals should be
connected to the distribution terminals by pair of twisted and/or shielded wires. Each load should be
separately c
onnected to the remote distribution te
r
minals (see Fig.3
-
13).
If remote sensing is required, the sensing wires should be connected to the distribution terminals or at
the most critical load.
3.9.11
Grounding outputs
Either the positive or negative output term
inals can be grounded. To avoid noise probems caused by
common
-
mode current flowing from the load to ground, it is recommended to ground the output
terminal as close as possible to the power supply chassis ground.
Always use two wires to connect the load
to the power supply regardless of how the system is
grounded.
