3.1.4 Ventilation Design
The air inlets (“Air-in” in the following figure) are located around of the container to satisfy the
volume requirements of air supply.
Hot air is exhausted via air ducts “Air-out” in the following figure.
Inverters are the main heating devices inside the container. The ventilation system is designed as
cool air coming inside from the bottom of the container and hot air getting outside the container
from the top of the container. Hot air emitted by the inverters, and hot air of the container internal
cooling fans is extracted out of the container through the air ducts on top of the container (“Air-out”
in the following figure).

3.1.5 Cable Entry Design
For convenient cable connection in the field, all cables among the container internal devices are
connected before delivery.
AC cables for connection of the container and the external devices are routed through the bottom
of the container. All cables come into or out of the container should be protected properly, for
example, cable pipe to prevent damage by rodents. After cable connection, all cable entries should
be sealed by fireproof mud or other appropriate materials.
The container bottom cable entries are shown below.
