3.6.2 EXTERNAL POWER PROGRAMMING USING A 0-10 VDC VOLTAGE
SOURCE
A DC voltage source for remote power programming is connected
between J1-13 (P_PROG) and return terminal J1-9 (GND). The voltage
coefficient for 10V remote power programming is 10 volts = 100% of rated
output power. See Figure 3-16 for connection requirements.

REMOTE SENSING
Remote voltage sensing is recommended at all times, whether you
connect sensing leads to the load or directly to the output terminals.
Remote sensing at the load provides the best load regulation.
In applications where the load is located some distance from the power
supply, or the voltage drop of the power output leads significantly
interferes with load regulation, remote voltage sensing should definitely be
used.
The voltage accuracy specifications are valid only with remote sense
connected. Disconnecting the remote sense leads will introduce an error,
with the output voltage increasing.
To use remote voltage sensing, connect the power supply as described
below. See Figure 3-17 for connection requirements.
Connect sensing leads from the load positive to J3-1 and the load
negative to J3-3. A shielded, twisted-pair, hookup wire is recommended to
avoid potential noise interference.
