Safety and Warning Instructions
Please read the Product manual carefully and observe all safety
and warning instructions, before the installation and putting into
operation of the frequency transformer. Keep this Product
Manual always at your finger tips in the vicinity of the frequency
inverter.
Definition of the instructions:
In the case of non-observance of these instructions,
death, severe injuries or considerable damage may occur.
In the case of non-observance of these instructions,
slight injuries or damage may be incurred.
Warning!
Attention!
General
During operation ensure that the power supply is
constant.
· This frequency inverter generates dangerous electric voltages
and controls rotating components that may become
dangerous. In the case of non-observance of the instructions
in this Manual, death, severe injuries or considerable damage
may be incurred.
· The installation, putting into operation and maintenance of
these drives is permitted to be undertaken only by technically
suitable persons who are completely familiar with the mode
of operation of the equipment and of the machine.
· The devices are equipped with intermediate circuit capacitors
which have dangerously high voltage rates even after having
been disconnected from the mains. You must wait at least
fifteen (15) minutes after having disconnected the voltage
before you can open the device and start working. It is
important to note that no live components are contacted.
· The earthing safety measures serve only the protection of the
frequency inverter and not for the protection of persons.
Three-phase frequency transformers are - according to VDE
0160 - not allowed to be connected with current-operated
earth-leakage circuit breakers because in the case of a
possible direct current component (direct current load). In the
case of such trouble the sensitivity of the current-operated
earth-leakage circuit breaker is reduced. As a protective
measure, the regulations of VDE 0160 are to be observed.
Earth the frequency inverter at the connection
provided for this purpose.
Do not come into contact with your hands or objects
components within the enclosure - when the device is
connected to the mains or if the intermediate circuit is still not
discharged. Do not work at the wires and do not check any
signals as long as the device is connected to the mains.
Warning!
Warning!
Warning!
Be particularly careful when the automatic restarting device is
activated. Install on the mains side a swit which is inactivated in
the case of a mains failure and which can be switched on when
voltage becomes available again only by manual operation, in
order to prevent injuries through uncontrolled restarting of the
frequency transformer after a mains failure. Earth the frequency
transformer at the corresponding connection.
Make sure that the input voltage complies with the
voltage stated on the type plate of the machine. Influences of the
environment, such as high temperatures, air humidity are to be
avoided in the same way as dust, oil and aggressive gases.The
place of installation should be a well ventilated location not
exposed to direct sun rays. Install the device at a vertical, fire-
resistant wall which does not transmit any vibrations. Do not
connect any mains voltage to the terminals U/T1, V/T2, W/T3.
· Please contact the manufacturers of the motors or machines
when standard motors with frequencies >60 Hz are to be
operated.
· All frequency transformers are tested regarding voltage
resistance and insulation resistance measurements. Insulation
resistance measurements are allowed to be carried out, e.g. in
the scope of inspections, only between the power terminals
and the ground. Do not carry out any insulation resistance
measurements at the control terminals.
· Enter the operation signals START / STOP via the control
terminals or the control panel and not by switching the mains
or motor contactor. Do not install any capacitors or excess
voltage distribution-type arresters into the motor input lines.
In order to safeguard safe and reliable functioning of
your Klingenburg Frequency inverter, all applicable safety
regulations, e.g. accident prevention regulations, VDE
regulations, etc. must be strictly observed. On account of the
fact that these regulations are differently handled in various
countries, the user is required to observe the requirements which
are applicable in his case. Klingenburg GmbH cannot warrant the
user from the duty to exactly follow the latest safety regulations
applicable in his case.
· The technical data and descriptions in this Operation Manual
have been compiled according to our best knowledge. Product
improvements are introduced all the time - Klingenburg GmbH
reserves the right, for this reason, to carry out such alterations
without prior notification.
· The instructions in this Operation Manual have been compiled
with great care. Should, in spite of everything, defects or
damage be incurred through the utilization of these
instructions, then Klingenburg GmbH cannot be held
responsible for any damage of this type.
