3.9.9. 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 the remote distribution
terminals (see Fig.3-6).
If remote sensing is required, the sensing wires should be connected to the
distribution terminals or at the most critical load.

3.9.10. Grounding Outputs
Either the positive or negative output terminals 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.
3.10. Local and Remote Sensing
The rear panel J2 sense connector is used to configure the Power Supply for local or
remote sensing of the Output voltage. Refer to Fig. 3-7 for sense connector location.
WARNING
All models shall not float outputs more than +/- 600VDC above/below
chassis ground.
WARNING
OUTPUT TERMINAL GROUNDING
There is a potential shock hazard at the RS-232/RS-485, IEEE port
and LAN port when using power supplies with rated or combined
voltage greater than 400V with the Positive Output of the power
supplies grounded. Do not connect the Positive Output to ground
when using the RS-232/RS-485, IEEE or LAN interfaces under the
above conditions.
