Inverters for control cabinet installation are designed for IP20 and IP31 degrees of protection. For some devices, not only is the easy installation mode possible, but also the ability to use the cold-plate or push-through installation technique. The devices can be installed one after the other to save space, and they can be used in a DC bus operation, keeping the wiring efforts to a minimum.
Thus, topologies can be clearly arranged even in the smallest spaces. All other control components, like the controller, the I/O system, are mounted right next to the inverters.
