5.4.2 Mounting
procedures
Since mounting the HDD depends on the system cabinet structure, determine the work procedures
considering the requirements specific to each system. The general mounting method and items to
be checked are shown below.
See Section 4.1 for the details of requirements for installing the HDD.
1) With a system to which an external operator panel is mounted, if it is difficult to access the
connector after the HDD is mounted on the system cabinet, connect the external operator
panel cable before mounting the HDD.
2) Fix the HDD in the system cabinet with four mounting screws as follows:
•
The HDD has 10 mounting holes (both sides: 3
× 2, bottom: 4). Fix the HDD by using
four mounting holes of both sides of the HDD or the bottom. (See Figure 4.5)
•
Use mounting screws of which lengths inside the HDD are 5.0 mm ± 0.5 mm when the
screws are tightened (see Figure 4.4).
•
When mounting the HDD, be careful not to damage parts on the PCBA.
3) Confirm the DE is not touching the frame on the system side excluding the screw installing
part after tightening the screws. At least 2.5mm of clearance is required between the DE and
the frame. (Indicated in Figure 4.4)
4) When using an electric screwdriver, use an electric screwdriver that does not apply a force on
the HDD that would exceed the HDD specifications.
