Introduction to the manual
Contents of this chapter
This chapter contains information on the manual.
Applicability
This manual is applicable to ACS880-7107LC DC feeder unit. The unit is a part of a complete
multidrive system.
Safety instructions
Obey all safety instructions delivered with the drive.
•Read the complete safety instructions before you install, commission, use or service
the drive. The complete safety instructions are given in ACS880 liquid-cooled multidrive
cabinets and modules safety instructions (3AXD50000048633 [English]).
•Read the software-function-specific warnings and notes before changing the default
settings of a function. For each function, the warnings and notes are given in the section
describing the related user-adjustable parameters.
•Read the task-specific safety instructions before starting the task. See the section
describing the task.
Target audience
This manual is intended for people who plan the installation, install, start up and do
maintenance work on the drive, or create instructions for the end user of the drive concerning
the installation and maintenance of the drive.
Read the manual before working on the drive. You are expected to know the fundamentals
of electricity, wiring, electrical components and electrical schematic symbols.

Introduction to the manual 9

Categorization by number of strings and option code
The number of strings identifies information which concerns only a certain DC feeder unit
design: the unit with one, two or three parallel strings (ST1, ST2 or ST3). The identifier is
shown on the type designation label and in the technical data for each DC feeder unit type.
The option code (option +A123) identifies information which concerns only a certain optional
selection. The options included in the unit are listed on the type designation label.
Use of component designations
Some device names in the manual include the item designation in brackets, for example
[Q20], to make it possible to identify the components in the circuit diagrams of the drive.
