Introduction
5.1.3 Installing the RFI Filter for the Power Module
When the AM600 series modules are used in environment with strong interference sources (for example
,
AC drive)
,
you are advised to use an RFI 󶍾lter to suppress noise.
RFI 󶍾lter must be installed as close as the AM600 power module as possible and mounted to the
conductive backplate with screws to ensure properly grounding. In principle
,
the input cables of RFI 󶍾lter
must be separated from the output cables of RFI 󶍾lter to prevent the noise of the cables at the front-end
of the 󶍾lter from being directly coupled to the cables at the back-end of the 󶍾lter.

5.1.4 Insulation Transformer
The insulation transformer is a component that suppresses conducted noise (especially surge noise that
may cause PLC malfunction). As a surge noise suppression device that reduces the impact of lightning
,
the insulated transformer is connected as shown in the following 󶍾gure.
