Vibration / Impact
Of all the panel computer components, the
hard disk is most vulnerable to vibration and
impact. Most hard disk problems are caused
by vibration or impact.
Generally, the vibration resistance and impact
resistance guaranteed by the hard disk
manufacturer is “4.9 m/s
2
” and “147 m/s
2
”
respectively. (For exact values, refer to the
manual for each product.)
Since the head of the hard disk is always
moving at a distance of approximately 0.01 to
0.02
µ
m from the disk surface, it must be
handled carefully.
Particularly when the hard disk is in
operation, the head moves above the data
area being used. Therefore, if an impact is
applied to the hard disk, the disk surface may
be damaged.
The panel computer cannot be used in a
system that may vibrate during operation.
Never attempt to move the system with the
panel computer power supply turned ON.
(1) Keep any system or control panel that
includes this product free from vibration.
(2) If a system or control panel that includes
this product is transported, vibration or
impact may be applied to the product
during transport, causing a failure or
problems in the product.
• Pack the product in a dedicated con-
tainer and transport it separately.
• Before mounting the product in a sys-
tem, first install the system.
(3) If the product is mounted in a movable
table or system, vibration or impact is
applied to the product when it is moved,
causing a failure or problems in the
product.
• Never attempt to move the system
when the product is in operation.
• When moving the system during a
stoppage, specifically when crossing a
cable on the floor or a groove, be care-
ful not to apply impact or vibration.
