Introduction to the manual
Contents of this chapter
This chapter contains information on the manual.
Applicability
This manual is applicable with the DC incoming units, ACS880-7207LC and ACS880-7307LC.
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.

Operation principle and hardware

Contents of this chapter
This chapter describes the intended use and construction of DC incoming units
ACS880-7207LC and ACS880-7307LC. The chapter also presents the type designation
label and the type code.

Operation principle and hardware description 13

Operation principle
The DC incoming unit provides connection between two DC systems. The two most common
applications are:
•connection of an external DC system to the drive DC bus (for example a connection point
for a generator)
•tie-bus connection, that is, division of the drive DC bus system in two or more parts.
For both applications, it is possible to use either ACS880-7207LC or ACS880-7307LC
incoming DC unit:
•ACS880-7207LC can isolate (disconnect) the two DC systems, and make and break load
currents. It can also break fault currents at certain extent.
•ACS880-7307LC can only isolate (disconnect) the two DC systems. It cannot make or
break load current or break fault current.
The main component both in the ACS880-7207LC and ACS880-7307LC units is a DC
isolator/breaker. The size and the connection of the DC isolator/breaker vary depending on
it's intended use.
