Danfoss VLT AHF005, Design Manual

Page: 6 / 59

2.1.4 EMC-Directive 2004/108/EG
The Danfoss frequency converters comply with the
requirements of the EMC -Directive. The AHF are inherently
benign equipment, that means that they do not produce
electromagnetic disturbances, consisting only of passive
components. Therefore, AHF are not within the scope of the
EMC-directive. Though, the Danfoss frequency converters in
combination with AHF will observe the requirements of the
EMC-Directive.
2.1.5 Warnings
WARNING
Improper installation of the filter or the frequency converter
may cause equipment failure, serious injury or death. Follow
this Design Guide and install according to National and Local
Electrical Codes.
WARNING
Never work on a filter in operation. Touching the electrical
parts may be fatal - even after the equipment has been
disconnected from the drive or motor.
WARNING
Before disconnecting the filter, wait at least the voltage
discharge time stated in the Design Guide for the
corresponding frequency converter to avoid electrical shock
hazard.
CAUTION
When in use the filter surface temperature rises. DO NOT
touch filter during operation.
CAUTION
To prevent resonances in the DC-link, it is recommended to
disable the dynamic DC-link compensation by setting
14-51 DC Link Compensation to OFF. See chapter 7 How to
Programme the Frequency Converter .
CAUTION
Temperature contactor must be used to prevent damage of
the filter chokes caused by over temperature. An immediate
stop or a controlled ramp down within 30 sec. has to be
performed to prevent damage of the filter chokes.
NOTE
Never attempt to repair a defect filter.
NOTE
The filters represented in this Design Guide are specially
designed and tested for operation with Danfoss frequency
converters (FC 102/202/301 and 302). Danfoss takes no
responsibility for the use of the filters with third party
frequency converters.
WARNING
Non - authorized removal of required cover, inappropriate
use, incorrect installation or operation, creates the risk of
severe injury to persons or damage to material assets.
CAUTION
All operations concerning transport, installation and
commissioning as well as maintenance must be carried out
by qualified, skilled personnel (IEC 60364 and CENELEC HD
384 or IEC 60364 and IEC-Report 664 or DIN VDE 0110.
National regulations for the prevention of accidents must be
observed).
NOTE
According to this basic safety information qualified skilled
personnel are persons who are familiar with the assembly,
commissioning and operation of the product and who have
the qualifications necessary for their occupation.
NOTE
The filters are components, that are designed for installation
in electrical systems or machinery.
When installing in machines, commissioning of the filters (i.e.
the starting of operation as directed) is prohibited until it is
proven, that the machine corresponds to the regulations of
the EC Directive 83/392/EEC (Machinery Directive); EN 60204
must be observed.
NOTE
Commissioning (i.e. starting operation as directed) is only
allowed when there is compliance with the EMC-Directive
89/336/EEC.
The filters meet the requirements of the Low-Voltage
Directive 73/23/EEC. The technical data and information on
the connection conditions must be obtained from the
nameplate and the documentation and must be observed in
all cases.
NOTE
The filter must be protected from inappropriate loads. In
particular; during transport and handling: Components are
not allowed to be bent. Distance between isolation must not
be altered. Touching of electronic components and contacts
must be avoided.
