Agency approval CE EMC immunity and emissions requirements were met using shielded wiring on the RS-485,
analog output and signal input lines. The shields were connected to earth ground at the Eclipse
end of the shields.
Conducted emissions requirements were met assuming that the AC signal input would not be
connected directly to the AC mains.
The measurement error during RF immunity testing was less than ±5% of full scale.
In addition, models with an AC signal input had measurement error of less than +25% of full scale
during RF immunity testing of the RS-485 at frequencies below 1 MHz.
