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.
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.3-14 for sense connector location.
3.10.1 Sense wiring
WARNING
Models up to 60VDC Rated Output shall not float outputs more than
+/-60VDC above/below chassis ground. Models > 60VDC Rated Output
shall not float outputs more than +/-600VDC above/below chassis
ground.
WARNING
OUTPUT TERMINAL GROUNDING
There is a potential shock hazard at the RS232/485 and the IEEE ports
when using power supplies with rated or combined voltage greater than
400V with the Positive Output of the power supplies is grounded. Do not
connect the Positive Output to ground when using the RS232/485 or
IEEE under the above conditions.
WARNING
There is a potential shock hazard at the sense connector when using a power
supply with a rated output voltage greater than 40V. Local sense and remote
sense wires should have a minimum insulation rating equivalent or greater
than the maximum output voltage of the power supply. Ensure that the
connections at the load end are shielded to prevent accidental contact with
hazardous voltages.
