1. ETERNUS AB/HB Installation

Installation Environment

Installation Environment
Sufficient consideration of the installation environment should be taken to ensure proper use of the
ETERNUS AB/HB. Using the ETERNUS AB/HB in an environment that does not satisfy the installation
environment requirements may cause a failure to occur with the ETERNUS AB/HB.

Air Conditioning

It is important to consider the flows of cooling air (intake air and exhaust air) for the installation loca-
tion of the ETERNUS AB/HB. The temperature in some ETERNUS AB/HB 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 taking into consideration the room size, whether other stor-
age systems are installed, and how many people are present in the room.
Take the following points into consideration when installing the air-conditioning system:
●
Ambient Temperature
An ETERNUS AB/HB is cooled by taking in air through the front intakes and pushing out the
exhaust air through the rear of the ETERNUS AB/HB. If the intake air temperature does not meet
the ambient environment conditions, a temperature error occurs and the power of the ETERNUS
AB/HB is shut down.
- Front intake air temperature
The air temperature of the front intake varies depending on the model. Refer to the environ-
mental conditions that are listed in
- 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.
