Introduction to the manual

Contents of this chapter

This chapter gives basic information on the manual.

Applicability

The manual is applicable to ACS880-1604LC DC/DC converter modules for user-defined

cabinet installations.

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 multidrives 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 15

Categorization by frame size and option module

Some descriptions, instructions and technical data which concern only certain module

or frame sizes are marked with the size identifier (such as "2×R8i", etc.). The marking

derives from the quantity and basic construction of the converter modules that form

the converter unit. For example, frame size "2×R8i" indicates that the converter unit

consists of two frame size R8i converter modules connected in parallel.

The frame size is marked on the type designation labels. The frame size of each drive

module is also shown in the rating tables.

The instructions and technical data which concern only certain optional selections are

marked with option codes (such as +E205). 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.
