Appendix 3-6 EMC countermeasure parts
Appendix 3-6-1 Shield clamp fitting
The effect can be enhanced by connecting the cable directly to the earthing plate.
Install an earthing plate near each panel's outlet (within 10cm), and press the cable against the earthing
plate with the clamp fitting.
If the cables are thin, several can be bundled and clamped together.
Securely earth the earthing plate with the frame ground. Install directly on the cabinet or connect with an
earthing wire.
Contact Mitsubishi if the earthing plate and clamp fitting set (AERSBAN- SET) is required.

Appendix 3-6-2 Ferrite core
A ferrite core is integrated and mounted on the plastic case.
Quick installation is possible without cutting the interface cable or power cable.
This ferrite core is effective against common mode noise, allowing measures against noise to be taken
without affecting the signal quality.
