6-2 PANEL INSTALLATION
• Ventilation holes are drilled through the top, bottom and side faces of the instrument
rack for natural cooling. When mounting the instrument rack within the panel, do not
close these ventilation holes. If closed, the temperature in the rack may rise to
shorten the service life of electronic parts used.
Do not place anything which interrupts ventilation within 200 mm from top and
bottom faces of the instrument rack.
Do not place the apparatus which generates heat under the instrument rack.
• Be careful when installing the instrument rack in a bad-ventilated closed box
(instrument panel).
It may cause shortening the life time of electronic parts because of marked rising in
temperature of the instrument rack in a bad-ventilated closed box which keeps the
heat in.
Cool down inside the box with a cooling fan or the like.
Especially when installing in a small closed box, use the forced-air cooling apparatus
like an electronic air conditioner.
(1) Insert the instrument rack from the front of the instrument panel.
(2) Insert 1 into the holes at the top and bottom of the instrument rack and slide it toward the
instrument panel.
(3) Insert 2 into the rear holes at the top and bottom of the instrument rack.
(4) Screw 3 into 2 and push 1 into the instrument panel.
• Avoid applying excessive force to the screws as this may deform the mounting
bracket.
