4.1.3Notes on mounting

(1)Mounting frame structure

To guarantee integrity of the IDD disk enclosure (DE) insulation once mounted on the frame inside the system, special attention must be given to the note below.

Note:

Generally, SG and FG are connected at one point in the system enclosure. Therefore, use following procedure to maintain the insulation when mounting the IDD.

a)Use the frame with an embossed structure or the like to avoid contact between the DE base and FG. Mount the IDD with making a gap of 2.5 mm or more between the IDD and the frame of the system.

b)As shown in Figure 4.6, the inward projection of the screw from the IDD frame wall at the corner must be 4 mm or less.
