To maintain EMC emission limits, cabling interconnecting the HA terminal and subsequent opto-coupler isolation,
must be no more than 1.9 m in length.

Loop four turns of this cable through a suitable small EMC ferrite toroid, and protect with a short length of large
diameter heat-shrink tube.

There is no similar length limit for cable following on from the opto-coupler isolation.
