3.10.1. Sense Wiring
3.10.2. Local Sensing
The Power Supply is shipped with the rear panel J2 sense connector wired for local
sensing of the Output voltage. See Table 3-4 for J2 terminals assignment. With local
sensing, the Output voltage regulation is made at the output terminals. This method
does not compensate for voltage drop on the load wires, therefore it is recommended
only for low load current applications or where the load regulation is less critical.

Terminal Function
J2-1 Remote positive sense (+S)
J2-2 Local positive sense. Connected internally to the positive output terminal (+LS).
J2-3 Not connected (NC)
J2-4 Local negative sense. Connected internally to the negative output terminal (-LS).
J2-5 Remote negative sense (-S).

WARNING
There is a potential shock hazard at the sense connector. 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.
