Installation
Measure a strand of twisted-pair copper wire (18 AWG) long enough to connect

the power converter to the switch. Ensure that the wire is long enough to loop
through the ferrite and still maintain 4 inches of thermal spacing between the
switch and the power converter.
Using an 18-gauge wire-stripping tool, strip both ends of the twisted pair wires to

0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.27 inch (6.8
mm) of insulation from the wire. Stripping more than the recommended amount
of wire can leave exposed wire from the power and relay connector after
installation. (See

Connect the other end of the positive wire (connected to VA) to the far-left power
converter DC positive-output connection, and connect the other end of the return
