MPI 40 Series - Mounting Recommendations; Dust Cover; Cooling

2.3 MOUNTING RECOMMENDATIONS
Due to its unusually small size and light weight, the Model 40 Series
can be installed in any convenient location, and in one of the three following
attitudes:
A. Vertical - Door opening left or right.
B. Horizontal - Door opening upwards.
C. Upright - Door opening forward or backwards.
Because the flexible disk drive is a precision device in which certain
critical internal alignments must be maintained, it is important that the
mounting scheme does not introduce significant stress on the drive. In
addition, mounting schemes involving more than two hard mounting points should
be avoided. Slide mounting generally satisfies the stress mounting require-
ments for the drive, as long as adjustable brackets or resilient members are
used to accommodate tolerances. Figures 2-1, 2-2, and 2-3 show all pertinent
dimensions for mounting the Models 41/42M(H), 41D/42D, and 41S/42S Disk
Drives, respectively.
I CAUTION I
Any mounting scheme in which the drive
is part of the structural integrity of
the enclosure is not permitted.
2.4 DUST COVER
Since the flexible disk drive is not provided with a dust cover, the
design of an enclosure should incorporate a means to prevent direct ingress
of loose items (e.g. dust, paper punch waste, etc).
2.5 COOLING
Heat dissipation from a single disk drive is normally less than 35
watts (93 Btu/Hr). When the drive is mounted so that the components have
access to free flow of air, normal convection cooling allows operation over
the specified temperature range. When the drive is mounted in a confined
environment, air flow may have to be provided to maintain specified air
temperatures in the vicinity of the motors, PCBA, and the diskette.
