ground terminal, CHAS-GND, of the DC OUTPUT connector, J2, as required to
maximize its effectiveness.
If the remote sense leads are not connected, the FPDC module will continue to
operate but the voltage at the load will no longer be precisely regulated. An
internal resistor network exists within the module that connects the output
terminals to the remote sense terminals. This network provides the
measurement of the output voltage when the remote sense leads are not
connected. However, since the voltage is now measured at the output
terminals, the voltage drop of the load wiring would no longer be compensated.

Input/output wiring must have a current carrying capacity compatible with the
current rating of the ReFlex Power™ system. The maximum current rating of a
wire is dependent on the materials used in its construction, and is primarily
limited by the insulation. The current must be limited so that the temperature rise
of the wire does not result in an operating temperature that exceeds the rating of
the wire.

Table 5-4 shows maximum current ratings, based on a cable of three
conductors, that will produce an approximate 30ºC temperature rise above
ambient. When wiring must operate in areas with an elevated ambient
temperature or bundled with other wiring, heavier gauges or higher
temperature-rated wiring should be used.
Although wire with higher temperature rated insulation will allow operation at
higher currents, the total voltage drop would also be increased for a given wire
gauge. For applications where voltage characteristics, such as regulation, are
important, it may be necessary to size the wire based on total voltage drop
instead of temperature rise.
