2.10.2 Cooling conditions for the Device on a table
Ensure at least 70 mm of space for airflow on all sides of the Device.
Do not block the ventilation slots. Otherwise, the internal heat is not discharged, which
might cause a fire. Ensure at least 70 mm of space from ventilation slots.
NOTE
When equipment with forced air cooling systems is installed near the Device,
interference due to the airflow from multiple devices can adversely affect the cooling of
the Device, which might result in a malfunction.
The exhaust airflow from nearby equipment might be drawn into the Device, and
the air intake temperature of the Device might exceed the environment
requirements.
When nearby equipment has too strong an intake or exhaust air system, reverse
air pressure might affect the Device airflow, decreasing the internal cooling
performance.
Maintain enough space or place a partition between equipment to prevent airflow
interference.
Note that if a partition is installed, it must be at least 70 mm away from the side panel of
the Device.
