As the cover in placed over the base, a connector on the cover mates with a connector on the base. The base contains a retractable input plug which is retracted on the base as the cover is installed and then extended from the retracted position through an aperture in the cover and fastened in place. The cover contains filtered vent holes in a wall that separates the base and cover, and evacuation ports are provided on the base and cover to create a vacuum in the RWA to test the electronics.
