## Dear Mr. Parker, Pursuant to the discussions in our webconference dated December20, 2011, and wi th reference to the comments made in the conference and the comments communicated by E-mail, the following minor changes have been made to the Data Center Transformer document.

1) The clause 2 (d) was “ the source voltage shall not be less than 5% of the rated voltage of the winding energized; and “

The revised wording now reads “ the source voltage shall not be less than 95% of the rated voltage of the winding energized; and”

The revised wording is correct wording and removes any ambiguity in the intent of the requirement. Revised wording does not relax qualification requirements.

2) The clause 3 (e) the additional requirement was “an electrostatic shield; or “

This clause is now removed.

This revision makes the qualification requirement more stringent.

I trust this document is now to be considered to be Final Document and to be

closed for further discussions and revisions.

Wish you all happy holidays and happy, peaceful and bright New

Year 2012.

With Kind Regards,

V. B. Tendulkar
