Explanation

A.6: Statement for conformance to Harmonics Guideline

Statement for conformance should be described in behind of operational manual's top sheet or something like that in an outstanding manner.

A.7: Submission of a Notice of Conformance to Harmonics Guideline

In order to grasp status of conformity of harmonics suppression requirement of JEITA member companies, we asked each member company to submit Notice of Conformance to our committee. Based on this letter, we are reporting member companies activity status for suppress harmonics and rate of passing our guideline annually to senior committee of IEC SC77A Japanese National Committee.

So, please submit us all your product's Notice of conformance to our committee. From now on, attachment test data sheet, which we have used to ask for submit, is no need to submit. However, we recommend keeping test data with Notice of conformance to Harmonics Guideline.

A.8: Difference between the Japanese Guideline for Reduction of Harmonic Emission and This Implementation Plan

The major differences between the Japanese Guideline for Reduction of Harmonic Emission and this plan for their implementation on the one hand, are indicated in the following table (Table A).
