Operation instructions controller
Pay special attention when the automatic restart is activated. To avoid injury from possible uncontrolled restart of the fre-
quency converter after a power outage, install a switch element on the grid side that de-energises in a power outage and can
only be turned on after return of voltage by manual confirmation (e.g., contactor, etc.).
Ensure that the input voltage corresponds with the voltage listed on the label. Environmental influences such as high tempera-
ture 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-flammable,
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 voltage 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 regula-
tions, such as accident prevention regulations, VDE regulations, etc,. must be observed.
As these regulations could contain different details within the German speaking areas, the user must observe the require-
ments 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. Pro-
duct improvements are constantly performed. For this reason, Klingenburg GmbH reserves the right to make such changes
without prior notice.
Despite the careful creation of these instructions, Klingenburg GmbH cannot be held liable for errors or damage which arise
from use of this manual.
10. Safety and precautions
Before installation and initial operation of the frequency converter, please read through the product handbook carefully and
observe all warnings and safety precautions. Make sure that the product manual is easily reachable in the area of the frequency
converter.
Definition of tips:
Warning!
Failure to comply with this information could cause death, severe bodily injury or significant physical damage.
Caution!
Failure to comply with this information could cause minor bodily injury or physical damage.
General:
During operation it must be ensured that the mains voltage is constantly on.
Warning!
This frequency converter creates dangerous electrical voltage and controls dangerous rotating parts. Failure to comply with the
information in this manual could cause death, severe bodily injury or significant physical damage.
The installation, initial operation and maintenance of this drive may only be performed by expert staff that are well versed in
the functionality and equipment as well as the machine.
The device contains intermediate circuit capacitors that also carry out switchover of dangerously high voltages on the grid side.
After switching off the voltage, wait at least 15 minutes before opening the device and working on it. Please be sure that no live
parts are touched.
The ground fault safety serves only as protection for the frequency converter and not as personal protection. In accor-
dance with VDE 0160 (German abbreviation for the Association for Electrical, Electronic &Information Technologies), the
three-phase frequency converter must not be operated on a leakage current circuit breaker, because a possible direct current
component will reduce the sensitivity of the leakage current circuit breaker in the event of a fault.
The provisions of VDE 0160 should be observed as protective measures.
Ground the frequency converter to the connection provided for it.
To avoid injury and damage, do not touch any parts within the housing – not with hands or any kind of object – when mains
voltage is present or the intermediate circuit capacitor is not loaded. Do not work on wiring or test signals when mains
voltage is present.
