3.9.10 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 terminals by a pair of twisted and/or shielded wires. Each load
should be separately connected to th e remote distribution terminals (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 terminals can be grounded. To avoid noise problems 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.
Note
Models up to 100V (including) can float between
outputs to ground no more than +/-100V. Models
above 100V can float between outputs to ground
no more than +/-600V.
Note
According to Safety Standards, Voltage < 60V
considered Non-Hazardous. Models up to 50V
(including) with floating outputs to ground less
than +/-60V considered as Non-Hazardous.
Warning
According to Safety Standards, Voltage >60V
considered Hazardous. All models include
models up to 50V with floating outputs to ground
more than +/-60V considered as Hazardous.

Anmerkung
Bei Modellen mit bis zu 100 V Nennausgangsspannung darf
der Potentialunterschied zwischen den Ausgängen und der
Gehäuse-Erdung nicht mehr als +/-100 V betragen.Bei
Modellen über 100V Nennausgangsspannung darf der
Potentialunterschied zwischen Ausgang und Gehäuse-Erdung
nicht mehr als +/-600V betragen.
Anmerkung
Gemäß den Sicherheitsnormen gilt eine Spannung < 60V als
ungefährlich.Modelle bis einschliesslich 50V mit erdfreien
Ausgängen unter +/-60V gelten als nicht gefährlich.
Gemäß den Sicherheitsnormen gilt eine Spannung > 60V
werden als gefährliche Spannung definiert.Alle Modelle
umfassen Netzteile bis zu 50V mit erdfreien Ausgängen
welche mehr als +/-60Vaufweisen, die als gefährlich gelten.
