Multiple load connection with distribution terminals
If remotely located output distribution terminals are used, the power supply output terminals should be
connected to the distribution term
i
nals by pair of twisted and/or shielded wires. Each load should be
separately connected to the remote distribution terminals (see Fig.3
-
14).
If remote sensing is required, the sensing wires should be connected to the dis
tribution terminals or at
the most critical load.
3.9.11
Grounding outputs
Either the positive or negative output terminals can be grounded. To avoid noise prob
l
ems 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.
WARNING
Models up to 60VDC Rated Output shall not float outputs more
than +/

60VDC above/below chassis ground. Models > 60VDC

not float outputs more than +/
