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 taking into consideration the room size, whether other storage 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 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 conditions, 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 35°C (or between 10 and 40°C for the ETERNUS DX600 S6).

  • Rear exhaust air temperature

    For example, when the intake air temperature is 35°C (or 40°C for the ETERNUS DX600 S6), the exhaust air temperature is 45°C or higher (or 50°C or higher for the ETERNUS DX600 S6).

    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 Installation Specifications.
