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 of 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 warnings of the software function before you take the function in use
or change its default parameter settings. Read the warnings of the parameter
before you change its default setting. Refer to the firmware manual.
Target audience
This manual is intended for people who plan the installation, install, commission 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 you work 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 (1×ST, 2×ST or 3×ST). 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 component designation in brackets (for
example, [Q20]). This will help you to identify the components in the circuit diagrams
of the drive.

Operation principle and hardware
description
Contents of this chapter
This chapter introduces the operation principle and construction of the DC feeder
unit.
Operation principle
The DC feeder unit provides a connection point for an external energy storage to the
common DC bus of a drive system. It enables transferring energy from a common DC
bus of a drive into an external energy storage and discharging energy back to the DC
bus. The energy storage can be, for example, a battery or super capacitor. The energy
storage media does not belong to the DC feeder unit product offering.
One DC feeder unit can contain one single or up to 3 parallel connected strings.
Parallel strings must be connected to separate energy storages. Each parallel string
must also have its own connection cabling.
Typically, the DC feeder unit is used in marine applications for heave compensation,
peak load compensation, propulsion supply in harbors, or energy storing instead of
an additional generator. The DC feeder unit can also be used in several other
applications where energy storing and reuse is needed.
