3.7. Environmental controls
The system is designed for the IP55 & NEMA 3R enclosure requirements for the operation in an outdoor environment at the
specified temperature ranges and up to 100% humidity non-condensing.
However, the converter and batteries have different environmental control strategies described as follows:
The C-Cab environmental control is maintained by a combination of forced air cooling with filters and heaters. Additionally,
the cabinet has double skin which prevents entry of water, maintaining IP degree.

The environment control is divided in different sub logic that acts at different level and that can be either controlled by
software logic or electro-mechanical actuators.
