Fixation with 2 plates Plate used to fixe the HVPS to the mechanical structure on the side. Top view
Lateralview ~56 mm ~56 mm ~53 mm Fixation of the HVPS To the fixation plate Fixation to the Back part of the PDM mechanical Structure. ~27 mm ZONE where to put the holes for the cables ZONE where to put the holes for the cables ~120 mm Fixation plate ~120 mm
Other possible zones for cables ~56 mm ~56 mm ZONE where to put the holes for the cables ZONE where to put the holes for the cables If HVPSs don’t lay directly on the fixation plate like bellow ~53 mm ~27 mm ZONE where to put the holes for the cables ZONE where to put the holes for the cables ~120 mm ~120 mm
Another (better) option: The plate could have half height and be fixed to the mechanical structure with 6 screws. ~56 mm ~56 mm ZONE where to put the holes for the cables ZONE where to put the holes for the cables ~53 mm ~60 mm OR ZONE where to put the holes for the cables
