Safety Warnings and Operating Information for Inverters
Introduction
Depending on their protection rating configuration, parts of inverters can have live, uninsulated and
hot surfaces during operation. If housing components, the control unit or terminal 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 regulations must also be observed.) For the
purpose of observance of the safety requirement 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 regulations. For further information
please refer to the documentation. In particular, please take care to observe all installation instructions
regarding 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 Yaskawa
representative.
Operation
In some systems it may be necessary to install additional monitoring and protective facilities 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 capacitors 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.
