5 . Use a standard screwdriver to loosen the screws holding the hot and neutral wires on the
side of the terminal block nearest the IEC plate (figure 3, below).
6 . Unscrew the IEC connector ground wire from the ground wire nut on the bare metal bottom
of the PS 123 enclosure.
7 . From the rear panel end, pull the IEC connector (figure 1) out of the enclosure.
8 . Thread the 18-gauge power wires through the length of the electrical conduit tube.

. Install the EMT adapter plate (figure 4) (with conduit attached) into the opening from which
you removed the IEC in step 7. Use the Phillips head screws (figure 1) that you removed in
step 2 to attach the EMT adapter plate.
10 . Slide the conduit nut (figure 4) over the bundle of wires exiting the conduit and onto the
conduit itself inside the PS 123. Hand-tighten the nut.
11. Attach and screw down the hot and neutral wires exiting from the conduit to their
corresponding screws on the terminal block.

W Ensure that you observe wire polarity. Figure 4 shows the location of the neutral and
hot poles on the mother board connector. The conduit wiring harness' neutral wire is
identified with a tag marked "N" (neutral).
12. Attach the ground wire from the conduit to the PS 123's bare metal plate bottom, securing it
by reattaching the ground wire nut.
13. Thread a tie wrap through the metal tab on the bare metal bottom of the PS 123, place all the
wires within its cradle, and zip the tie wrap over the bundle of wires.
14. Ensure that the conduit nut from step 10 (figure 4, above) firmly secures the conduit EMT
adapter plate to the power supply.
15. Use the six screws you removed in step 3 to secure the top cover of the PS 123 back onto its
bottom board (figure 2).
