PREFACE
This document
This document is intended as a reference for qualified and trained operators to transport,
install, use and maintain the medium voltage switchgear in a safe and economic way.
In this document the definition “medium voltage switchgear” is used to indicate a random –
but in actual practice existing – combination of DF-2 cubicles that, connected, form a
customer-specific transformation or distribution switchgear. For details, see “General
description”.
The chapters and sections are numbered. The page numbering (Form of the chapter
number and the page number) and the document code can be found at the bottom of each
page.
In the documentation the words “left”, “right”, “front” and “behind” are used to indicate a
specific part of the medium voltage switchgear. The starting point is always the position of
the operator, standing in front side of the switchgear.
