4. Connect the PDM to the power supply using Harness 734-012 for 120 V systems (734-013
for 220/230/240 V versions).
• Feed red and black wires through the side rail to the front of the power supply to prevent
wire damage when the front panel is inserted.
• Connect the separate red and black wires (with yellow female terminations) to plugs P2
(black) and P3 (red) on the EPS and plugs P5 (black) and P4 (red) on the SPS or RPS.
• Connect the white and black wires, which terminate together in a white snap-on connector,
to the bulkhead connector at the bottom of the EPS, SPS or RPS assembly, as shown in
Figure 2-34.
