Recommended Output Wire Size
A major consideration in making load connections is the wire size. The minimum wire size is
required to prevent overheating and to maintain good regulation. It is recommended that
the wires are sized large enough to limit the voltage drop at the maximum current rating of
the power source to no more than 0.25V per lead as the CFS senses at its output terminal,
not the load (Internal Sense Only).
Recommended wire gauges for copper wire are shown in the table below for highest current
rating by model, which occurs in AC mode and low voltage range. Aluminum wire is not
recommended. Keep the distance between the power source and load as short as possible
for best results.

Connecting a UUT
When setting up for a new test and connecting any equipment to the power source,
proceed as follows:
1.
Always make sure the power source is turned OFF at the POWER switch when
making any wire connections.
2.
Check that the output of the equipment under test is
OFF
and that the load is not
still energized. This applies in particular to DC Mode when driving a load with input
capacitance or batteries.
3.
Connect one end of each load wire to the L/+ and N/- output terminals on the rear
panel.
4.
Check the polarity of the connections and connect the other end of the load wires to
the input terminals of the equipment under test.
