Modular Dimensions in Standard Flexible Power Shelf Height Size

Modular Dimensions in Standard Enable multiple configurations racks. No real physical size change on rack.

Modular Dimensions (2)

Modular Dimensions (3) For 12V OCP rack, Dim. G-H should be: Dim. G-H, “Stop” to “RTN” G H For 12V OCP rack, Dim. G-H should be: 793.4 – 789.6 = 3.8 mm For 48V OCP rack, 652.6 – 645.0 = 7.6 mm This dimension is depended on used clip type / size. Table 2 12V Rack 48V Rack Dim. G-H, “Stop” to “RTN” 3.8 mm 7.6 mm
