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
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 teminal (+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
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.
