Connecting AC Power to the PCB
Make absolutely sure that your PAT-5 is unplugged!
The only thing that remains to do is to connect the fused 120 volt power to the
transformer. Locate the supplied piece of twisted white/black 22 AWG stranded wire.
1. Cut it to a 13” length.
2. On one end, untwist about three inches of the wires.
3. Cut off 3” of the white wire on that end.
4. Strip ¼” of insulation from the four ends of the wires. Twist and tin the four wire
ends.
5. Solder the short white wire to the fuse terminal closest to the side of the
enclosure. Recall that you removed the transformer violet-white and violet wires
from this fuse terminal in a previous step.
6. Solder the black wire from that end of the twisted pair to the convenience outlet
terminal (outlet C, terminal 1 in Figure 10). Recall that you earlier had
disconnected the black-white and black twisted pair from this terminal.
7. Route the black/white twisted pair along the same path as was previously taken by
the transformer wires, along the side of the chassis.
8. Insert the unconnected white wire into the AC1 eyelet from the component side of
the board and solder it on the solder side.
9. Insert the unconnected black wire into the AC2 eyelet from the component side of
the board and solder it on the solder side.
What if PAT5PM Is Installed?
The transformer wiring changes in this manual puts the power transformer windings in
series, rather than parallel. These changes are independent of the power switch re-wiring
undertaken in the PAT5PM (Power on mute) manual. Therefore, the wiring for this
power supply installation does not change if the PAT5PM is present or absent. In both
cases:
1. power supply white wire goes to the side of the fuse closest to the side wall.
2. Power supply black wire goes to outlet C terminal 1.
The difference between PAT5PM wiring (switching the power to the power supply) and
standard wiring (leaving the power supply always powered) remains independent of the
changes described in this manual.
Take a break
You have just reached a rather important milestone. Get up, walk around, say hi to your
significant other or the family pet. You’re about to apply power to the PAT5 to test the
power supply, and it’s always a good idea to have clear head before doing anything that
involves the AC mains.
