Installation Instructions
1)
Locate the FOI to the PSQ as shown; the power plug slides straight into the mating receptacle.
2)
Start the captive screws into the FOI face. Do not tighten completely until both are threaded.
3)
Tighten snugly the captive screws, evenly, drawing the faces together. The mounting face of the
FOI should be in uniform contact with the face of the PSQ.
Note: The PSQ‐4909 is shown. The PSQ‐2920, PSQ‐3920 and PSQ‐4920 Low Voltage power supplies do
not have the AC adapter cable.
