2.2 Mounting Hole Dimensions
As the MD800 series units are booksize units with equal height and width. mounting
holes with equal spacing are adopted. The longitudinal spacing of the mounting holes
is 172 mm and the transverse spacing is 50 mm. The recommended clearance for
good heat dissipation is at least 55 mm on the left and right and at least 200 mm on
the top and bottom of the mounting holes.
The following shows the example of mounting hole dimensions, in which one power
supply unit is connected to five drive units.
