Screening without a Screen Termination Kit
In order to meet radiated emissions a screen termination kit must be used. Screening without
a screen termination kit is only suitable for installation in a metal cabinet.
Should a Screen Termination Kit not be available, the inverter then can be screened using
the methodology shown in the figure below. This diagram shows both methodologies of
screening.
Note
The EMI illustration below is not to scale. The terminal cover on Frame Size D cannot be
