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).
3.10.3 Remote sensing
WARNING
There is a potential shock hazard at the sense point when using power
supply with a rated output voltage greater than 40V. Ensure that the
connections at the load end are shielded to prevent accidental contact with
hazardous voltages.
CAUTION
When using shielded sense wires, ground the shield in one place only. The
location can be the power supply chassis or one of the output terminals.
