Board Footprint and Mating Orientation
The 0399700104: This block mounts through-hole and mates horizontally with the board — the wire entry is parallel to the PCB surface, which keeps the overall height low in an enclosure. The 10.16 mm pitch and 4 positions per level define the board footprint: four holes on 10.16 mm centers, with the screw axis perpendicular to the board edge. The single-level design means all four terminations are on the same plane, simplifying routing for a power distribution rail.
