1.6 Installation Environment
Sufficient consideration of the installation environment should be taken to ensure proper use of the ETERNUS
DX. Using the ETERNUS DX in an environment that does not satisfy the installation environment require-
ments may cause a failure to occur with the ETERNUS DX.
1.6.1 Air Conditioning
It is important to consider the flows of cooling air (intake air) and exhaust air for the installation location of
the ETERNUS DX. The temperature in some ETERNUS DX storage systems may rise by taking in air exhausted
from other storage systems depending on how they are installed near each other. In addition, check if the
ambient temperature in the installation location always satisfies the usage environment temperature by tak-
ing into consideration the room size, whether other storage systems are installed, and how many people are
present in the room.
When installing air conditioning, consider the following:
● Ambient Temperature
An ETERNUS DX is cooled by taking in air through the front intakes and pushing out the exhaust air through
the rear of the ETERNUS DX. If the intake air temperature does not meet the ambient environment condi-
tions, a temperature error occurs and the power of the ETERNUS DX is shut down.
•
Front intake air temperature
Make sure that the front intake air temperature is between 10 and 40°C.
•
Rear exhaust air temperature
For example, when the intake air temperature is 40°C, the exhaust air temperature is 50°C or higher.
The necessary cooling capacity of air conditioning must be determined by taking the exhaust air cooling
into consideration.
Estimate the amount of heat in the exhaust air from the ETERNUS DX by using the heat generation amount
and exhaust air amount that are listed in "1.1 Installation Specifications" (page 11).
