Maintenance and operation
Warning!
Ensure that the input voltage corresponds with the voltage
listed on the label. Environmental influences such as high
temperature and high humidity are to be avoided as well
as dust, dirt and aggressive gases.
The install location should be a well-ventilated location
away from direct sunlight. Install the device on a non-flam-
mable, vertical wall that does not transmit vibrations. Do
not connect mains voltage to the output terminals U/T1, V/
T2, W/T3.
Please contact the motor or machine manufacturer if
standard motors with a frequency of > 60 Hz will be
operated.
All frequency converters are tested for dielectric strength
and insulation resistance measurements. Insulation
resistance measurements, for example, in the course of
inspection, must not be conducted between the power
terminals and earth. Do not carry out insulation resistance
measurements on the control terminals.
During operation it must be ensured that the mains volt-
age is constantly on. Control commands and operating
signals (such as start/stop) must only be implemented
via the control terminals or the control panel and not by
switching the mains supply or a motor contactor.
Do not install capacitors or overvoltage arrestors in the
motor lead.
Caution!
In order to guarantee that your Klingenburg frequency
converter operates securely and reliably, all respective
safety regulations, such as accident prevention regula-
tions, VDE regulations, etc,. must be observed.
As these regulations could contain different details within
the German speaking areas, the user must observe the
requirements that are valid for their area.
Klingenburg GmbH cannot exonerate the user from the
obligation to follow the most current safety regulations.
The technical data and descriptions in these operating
instructions are compiled according to the best of our
knowledge and belief. Product improvements are con-
stantly performed. For this reason, Klingenburg GmbH
reserves the right to make such changes without prior
notice.
Despite the careful creation of these instructions, Klingen-
burg GmbH cannot be held liable for errors or damage
which arise from use of this manual.
