PXE7300 Series IFE System Installation and Operator’s Manual

After wiring is complete, verify power is ONLY on pin 21 of the connector, and airframe ground on bot- tom connector pin 22. Failure to do so will cause serious internal damage and void PS Engineering's war- ranty.

To install the PXE7300, gently slide the unit into the mounting rack until the hold-down screw is engaged. While applying gentle pressure to the face of the unit, tighten the 3/32" hex-head in the unit until it is se- cure. DO NOT OVER TIGHTEN.

: Do not over-tighten the lock down screw while installing the unit in tray.
