2.6 Post Installation Checkout
After wiring is complete, verify power is ONLY on pin 25 of the J1 connector, and airframe ground on pin
13. Failure to do so will cause serious internal damage and void PS Engineering's warranty.
2.6.1 Operational Checkout
Apply power to the aircraft and avionics. Verify that the audio signal connected to the PA50 are provided
to the aircraft’s audio system. Verify that the unit is fully functional and in condition for safe operation.
2.7 Final Inspection
Verify that the wiring is bundled away from all controls and no part of the installation interferes with air-
craft control operation. Move all controls through their full range while examining the installation to see
that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in accor-
dance with good practices, with adequate strain relief. Ensure that there are no kinks or sharp bends in the
cables and coaxial cables. Verify that the cables are not exposed to any sharp edges or rough surfaces, and
that all contact points are protected from abrasion.
