12 Introduction to the manual
Read the manual before you work on the drive. You are expected to know the
fundamentals of electricity, wiring, electrical components and electrical schematic
symbols.
Categorization by frame size and option code
Some descriptions, instructions, technical data and dimensional drawings which
concern only a certain group of units are marked with the symbol of the frame size
(such as "D8D", "2×D8D" etc.). The marking derives from the quantity and basic
construction of the modules that form a supply unit. For example, frame size "2×D8D"
indicates that the supply unit consists of two frame size D8D modules connected in
parallel.
The frame size is marked on the type designation labels. The frame size of each module
is also shown in the rating tables of chapter Technical data.
The instructions and technical data which concern only certain optional selections are
marked with option codes (such as +A019). The options included in the drive can be
identified from the option codes visible on the type designation label.
Use of component designations
Some device names in the manual include the component designation in brackets (for
example, [Q20]). This will help you to identify the components in the circuit diagrams
of the drive.
