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.
