‹ Safety Precautions and Instructions
„ 1. General
Please read these safety precautions and instructions for use thoroughly before installing and operating this
inverter. Also read all of the warning signs on the inverter and ensure they are never damaged or removed.
Live and hot inverter components may be accessible during operation. Removal of housing components, the
digital operator or terminal covers runs the risk of serious injuries or damage in the event of incorrect installa-
tion or operation. The fact that frequency inverters control rotating mechanical machine components can give
rise to other dangers.
The instructions in this manual must be followed. Installation, operation and maintenance may only be carried
out by qualified personnel. For the purposes of the safety precautions, qualified personnel are defined as indi-
viduals who are familiar with the installation, starting, operation and maintenance of frequency inverters and
have the proper qualifications for this work. Safe operation of these units is only possible if they are used
properly for their intended purpose.
The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from the power. It
is therefore necessary to wait for this time before opening its covers. All of the main circuit terminals may still
carry dangerous voltages.
Children and other unauthorized persons must not be allowed access to these inverters.
Keep these Safety Precautions and Instructions for Use readily accessible and supply them to all persons with
any form of access to the inverters.
„ 2. Intended Use
Frequency inverters are intended for installation in electrical systems or machinery.
Their installation in machinery and systems must conform to the following product standards of the Low Volt-
age Directive:
EN 50178, 1997-10,Equipping of Power Systems with Electronic Devices
EN 60204-1, 1997-12Machine Safety and Equipping with Electrical Devices
Part 1: General Requirements (IEC 60204-1:1997)/
Please note: Includes Corrigendum of September 1998
EN 61010-1, A2, 1995Safety Requirements for Information Technology Equipment
(IEC 950, 1991 + A1, 1992 + A2, 1993 + A3, 1995 + A4, 1996, modified)
CE marking is carried out to EN 50178, using the line filters specified in this manual and following the appro-
priate installation instructions.
„ 3. Transportation and storage
The instructions for transportation, storage and proper handling must be followed in accordance with the tech-
nical data.
„ 4. Installation
Install and cool the inverters as specified in the documentation. The cooling air must flow in the specified
direction. The inverter may therefore only be operated in the specified position (e.g. upright). Maintain the
specified clearances. Protect the inverters against impermissible loads. Components must not be bent nor insu-
lation clearances changed. To avoid damage being caused by static electricity, do not touch any electronic
components or contacts.
