Safety Warnings and Operating Information for Inverters
Introduction
Depending on their protection rating configuration, parts of inverters can have live, unin-
sulated and hot surfaces during operation. If housing components, the control unit or ter-
minal covers are removed, incorrect installation and operation can lead to serious injuries
and damage to other installations. It is thus absolutely essential to observe all the warnings
and instructions in the operating manual. Installation, setup and maintenance should only
be performed by properly qualified staff. (IEC 364 / Cenelec HD 384 or DIN VDE 0100
and IEC 664 or DIN VDE. The applicable national safety and accident prevention regula-
tions must also be observed.) For the purpose of observance of the safety requirements
qualified staff are defined as individuals who are familiar with the installation, setup and
operation of the converters and who have the proper qualifications for this work.
Proper use for intended purpose
Inverters are designed for installation in electrical systems or machines. A converter
installed in a machine may only be activated if the machine conforms to the provisions of
EU directive 89/392/EEC (machine directives). EN 60204 must also be observed. The
converter may also only be operated if the requirements of the EMC directive (89/336/
EEC) are also satisfied. This frequency converter conforms to the requirements of the low-
voltage directive, 73/23/EEC. The harmonized standards of the prEN 50178/DIN VDE
0160 series have been applied, in combination with EN 660439-1 / VDE 06600 Part 500
and EN 60146 / VDE 0558. The specifications on the ratings plate and the specifications
and connection requirements described in the documentation must be observed at all
times.
Transportation and storage
All instructions for transport, storage and proper handling must be observed. Climatic and
environmental conditions must conform to the requirements of prEN 50178.
Installation
The converters must be installed and cooled in compliance with the regulations outlines
and referred to in the documentation. The cooling air flow direction is an important
requirement that must be observed. This means that the unit may only be installed and
operated in the specified orientation (e.g. upright). All distances specified must also be
observed. The converters must be protected against excessive stresses. No components
may be bent and no distances required for proper insulation may be changed. To prevent
the risk of static electricity damage never touch electronic components or contacts.
Electrical connections
All national safety regulations (e.g. VBG 4) must be observed when working on live
equipment. The electrical installation of the units must conform to the applicable regula-
tions. For further information please refer to the documentation. In particular, please take
care to observe all installation instructions as regards proper EMC immunity, e.g. for
shielding, earthing, location of filters and cable routing. This also applies for equipment
with CE approvals. Compliance with the EMC legislation limits is the responsibility of the
machine or system manufacturer.
RCCBs
For information on the use of RCCBs with inverters please contact your supplier or
Saftronics representative.
Operation
In some systems it may be necessary to install additional monitoring and protective facili-
ties to comply with the applicable safety and accident prevention regulations. The only
changes permitted are to the operator software of the inverters. Please note that the capac-
itors can remain charged for up to around 5 minutes after the frequency converter has been
disconnected from the power supply. You should thus always wait for a short period
before opening the unit and touching the electrical connections.
