2.7 Positioning inside the panel
The position of the controller in the electrical cabinet must be chosen so as to guarantee correct physical separation from the
power components (solenoids, contactors, actuators, inverters, ...) and the connected cables. Proximity to such devices/cables
may create random malfunctions that are not immediately evident. The structure of the panel must allow the correct fl ow of
cooling air.
