All measurements are taken from the outside edge of the machine frame,without covers, unless specifically described otherwise.2. Example 1 of the table shows floor loading for a maximum-weight frame instorage, where there is no space between frames on all four sides, and coversare installed. The ’a’, ’b’, and ’c’ dimensions represent the depth of the covers.When a system is stored, with no spaces between frames, the floor load ratingshould be at least 1000 kg/m 2 (200 lb/ft 2 ).If weight distribution clearances are overlapped, the customer should obtain theservices of a qualified consultant or structural engineer to determine floor loading.Service ClearanceUnder typical conditions,service clearances of adjacent products may be overlappedbut weight distribution areas should not be overlapped. Regardless of floor loading,minimum service clearances must be observed. The zSeries 800 requires 762 mm(30 in) of service clearance on all four sides of the machine.a , ,b ca aRearFrontWeight DistributionbcFigure 2-3.
