Introduction to the manual
Contents of this manual
This chapter gives basic information on the manual.
Applicability
This manual is applicable with ACS880-7407LC semiconductor switch units.
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.
