Installing Your PC in a 19" Cabinet or Rack (RI45 PII 19" Operation)
Layout
The installation height for your SIMATIC PC RI45 PII is only four ET
(height units = 177 mm, Figure LEERER MERKER). Therefore, special
installation assemblies are not required for installing this computer in a 19"
cabinet or rack. You must use four screws to fix the computer into position on
the cabinet's braces. However, you should under no circumstances mount the
computer just on these screws (without rack slide rails). Use the respective
manufacturer 's cabinet or rack slide rails or L-sections. Contact your cabinet
supplier directly regarding cabinet or rack installation.

Warning
!
Avoid extreme ambient conditions as far as possible. Protect your SIMATIC
PC from dust, moisture, and heat. (Refer to the "System Unit" section in the
Technical Description.)
Mount the device as safely as possible to prevent any danger (for example,
by falling over).
The clearance around the system unit must be at least 200 mm at the front
and rear, so that the system unit is sufficiently ventilated.
Make certain that the ventilation slots for the system unit and the monitor
are not covered.
Make certain that the sliding door in front of the drives is closed during
operation. If the sliding door is not closed, insufficient air is drawn through
the ventilation slots to cool the interior of the system unit.
