1.General information
Before you start with the installation and the starting up of the inverter, please read this manual carefully
and pay special attention to the notes and suggestions.
This manual must be made available to every user. Before working with the unit the user must become
familiar with it. This specially applies to the knowledge a nd observance of the following safety and
warning indications.
Used symbols:
Danger, warning
This symbol is used when the life or health of the user is in danger or a considerable damage to property
can occur.
Attention, essential measure
This symbol is shown on places of the manual, which are to be particularly consid ered for safe and
disturbance-free operation of the inverter.
2.Safety instructions
All instructions stated in this chapter are important for t he security of users and machines or systems
and should absolutely be considered.
2.1.General safety instructions
Inverters work with high voltages, which can cause death or serious injury by touching them. Depending
on the degree of protection of the inverter, in operation they may have live, uninsulated and possibly
also moving or rotating parts, as well as hot surfaces. In case of an inadmissible removal of the required
covers, an improper use and a wrong installation or operation, there is a danger of serious personal
injury and damage to property.
All operations serving transport, installation and commissioning as well as maintenance are to be
carried out by skilled technical personnel (observe IEC 364 or CENELEC HD 384 and national accident
prevention rules!). For the purposes of these basic safety instructions, "skilled technical personnel"
means persons who are familiar with the installation, mounting, commissioning and operation of the
product and have the qualifications needed for the performance of their functions.
2.2.Intended use
The application of the inverter described in this operating manual exclusively serves for the purpose
of continuously variable speed control of three-phase motors.
Inverters are components designed to be used in electrical installations or machinery.
Commissioning of the inverter (e.g. the starting of normal operation) is prohibited until the system has
been proved to conform to the provisions of the directive 89/392/EEC (Machinery Safety Directive -
MSD) and the 89/336/EEC (EMC directive).
The inverter meets the requirements of the low-voltage directive 73/231/EEC. They are subject to the
harmonized standards of the series EN 50178.
The operator of the system is solely liable for damage resulting from improper use of the inverter.
ATTENTION!
BERGES electronic
09.07.2001 Operating manual ACM D2/S2 3
2.3.Transport, storage, installation
The inverter must be protected against inadmissible mechanical loads. No components must be
bent and no insulating distances must be altered during transportation or handling. The inverters
are containing electrostatic sensitive components which are liable to damage through improper
use. Do not touch electronic components an d electrical contacts. Do not switch on inverters with
mechanical damaged electrical or electronic components, the accordance with the applied directi-
ves is no longer guaranteed in this case. With the installation of the inverter attention is to be paid
to the prescribed minimum distances as well as to a sufficient cooling. The climatic conditions shall
be in conformity with E N 50178.
2.4.Electrical connection
Before performing any installation work the system must be insulated from the mains supply and
protected accordingly.
After switching off the line voltage, wait for at least 5 minutes un til the DC-link capacitors are
discharged. Only then it is allowed to work on the device. In case of malfunctions, the discharge
time could be exceeded substantially.
Because of a possible leakage current > 3.5mA from the installed EMC-filter, the inverter is designed
only for permanent connection. For size and layout of the GND (earth) conduc tor also see EN
50178.
The inverters are designed to be installed in a switchgear cabinet and may only operate when
connected with earth-potential.
For a trouble-free operation of the inverter, the installation requirements and notes in this manual
are to be considered.
When using residual-current-operated circ uit-breakers pay attention to the compatibility with the
inverter. Depending on the type of the device the foll owing rules apply:
•Single-phase inverters: pulse-current sensitive (type A) or all-current sensitive (type B) residual-
current-operated circuit-breakers are admissible.
•Three-phase inverters: only all-current sensitive (type B) residual-current-operated circuit-brea-
kers are admissible.
Otherwise another protective measure such as separation from the environment by double or
reinforced insulation, disconnection from the mains or similar are to be used (EN 50178). The trigger
current of the residual-current-operated circuit-bre akers must be sufficiently dimensioned since
capacitive leakage currents (cable screens, filters) can e asily lead to false triggering.
2.5.Operating instructions
The inverter can be configured to restart automatically in case of an error. If necessary, the system
must be equipped with additional monitoring or protective features to avoid resulting dangers (see
accident prevention rules etc.).
The motor can be stopped by switching off the setpoint or deactivating the enable input. If required
for safety reasons, an inadvertent restart can be preven ted disconnecting the inverter from the
mains supply.

12.Installation
12.1.Installation
The frequency inverters are designed for installation in a switchgear cabinet and for
permanent connection.
The inverter must be installed so that the heat sink is facing to the right. Only in this way sufficient
cooling is guaranteed.
If the inverter has to be installed in a different position, external coolin g is required for full capacity
utilization.
BERGES inverters are generally designed so that they can be operated at ambient temperatures
from −5 °C to +45 °C and at a relative humidity of up to 90%.
Formation of condensation must be avoided!
Please contact BERGES if the above values are exceeded. A heat build-up at the inverter during
operation must be prevented. The internal air circulation may possibly be in sufficient if the unit is
installed in a control cabinet with a small volume.
The units should never be installed in the proximity of corrosive or flammable gases, conductive
dust or large magnetic and electric fields.
The inverter should be installed in a location that is largely free of dust, steam and vibrations.
Operation of the units in the presence of abrasive dust, steam, condensate, oil mist or air containing
salt will reduce their useful life.
Pay close attention during installation to ensuring that no objects (such as drilling swarf, wire or
anything else) fall into the unit. Otherwise a device fault cannot be excluded, even after longer
periods of operation.
12.2.Mains power connection
To guarantee lasting operating safety and reliability, the inverter must be connected expertly in
accordance with the valid electric standards. Attention must be paid to good insulation from earth
potential on the power terminals.
Connect a single phase mains power supply with a rated voltage between 220V and 240V or a
three-phase mains power supply with a rated voltage between 380V and 460V
(5.5kW 380...415V)
40..70Hz to the mains power connection terminals L1, N or L1,L2,L3 and PE respectively (TN-C
System).
L 1 (phase) - N 220...240V 40...70Hz PE = earth
L1 L2 L3 (phases) 380...460V
(5.5 kW 380...415V)
40...70Hz PE = earth
Ensure a voltage balance to earth when feeding in the mains power through an insulating
transformer (star point earthed) or use the vector group “DY5” in the case of single- phase inverter
power supply.

12.3.Motor connection
Connect the motor cable to the
U, V, W
and PE terminals.
The inverter will be deactivated in the event of a short circuit at the terminals
U, V, W.
We recommend PTC evaluation using commercially available devices to achieve effective protection
of the motor.
If interrupting contacts (e.g. contactors or motor protection switches etc.) have to be installed between
the motor and inverter, the circuit must be configured so as to ensure that the
ENABLE
signal (terminals
10/11) is deactivated
before
separation of the inverter/motor connection. A relay switching time of
approx. 30 ms suffices.
Long motor cables (> 20m) in connection with high voltage peaks caused by the fast switching output
stages of the inverter may endanger the motor insulation. In such cases we recommend to use suitable
filter measures (e.g. motor chokes or dU/dt filters) to protect the motor.
12.4.Interference supp ression measures / EMC
(electromagnetic compatibility)
12.4.1.General information
Inverters are electronic devices which are used in industrial and commercial sys tems. In accordance
with the EMC-directives 89/336/EEC the inverters are not designed for independ en t operation. Thus
inverters should be used for further processing thro ugh competent machine/system manufacturers.
By this, the devices do not require a CE-marking. The proof of the conformity of the machine/system
with the required EMC-directives must be furnished by the manufacturer or operator of the system.
The inverters of the ACM series are equipped with an internal filter and designed to be used in class
"A" environments (first environment, restricted distribution) according to the product standard EN
61800-3.
The evaluation of the conformity took place in a practical structure having taken into account the
following installation notes.
Voltage peaks produced by other devices connected at the mains supply can possibly disturb or even
damage the inverter. Input ch ok es (option) can be used to protect the inverter against these voltage
peaks (caused e.g. by switching off of high loads from the mains).
12.4.2.Installation notes
During operation, electrical/electronic devices can influence or disturb each other via power supply or
other metallic connections.
The electromagnetic compatibility of the system is highly influenced by the manner of the installation.
Measures for the grounding, shielding and filtering are to be particularly considered. By paying attention
to the following installation notes it can be assumed that the EMC limit values for the system/machine
are kept.
•Inverters and optional components like input or output chokes must be in metal-to-metal contact
with the grounded mounting plate using the whole surface if possible. Use prefera bly galvanized
mounting plates. Painted mounting surfaces must be free from paint.
•Lay the mains, motor and control cables in large distance from each other.
•Use shielded motor cables connected to earth on both sides.
•Connect the motor cable shield with the PE terminal located in the terminal box of the motor. Use
possibly metallic cable glands.
•Optional output chokes must be mounted close to the inverter and connected with shielded cables.
Connect the cable shield to earth on both sides.
•Use shielded control cables connected to earth on both sides.
•Unshielded control cables must be twisted.
•Connect the cable shields either with the mounting plate using ground clamps and contacted over
as large an area or at an equipotential bar (see picture).
•Use a central earthing point for the whole machine/syste m (mounting plate). Connect this point to
earth using earth cables with a large cross section or fl at copper braids.
Remove any
paint or varnish!

•Do not extend the shields with single wires and do not interrupt them if possible.
•When constructing the switchgear cabinet or the system, separate the power section from the
control section. Eventually provide a shield between power and control section.
•Wire inductive switching elements (coils of contactors or relays) with RC-elements, free-wheeling
diodes or varistors.
12.5.Mains back-up fuses
External upstream fuses are required to protect the cables and the unit i tself. The fuses must be
dimensioned so as to permit starting u p and normal operation of motors. To guarantee this, we
recommend the use of the followings slow-blow fuses:
Mains input 1 x 230V
0.37kW 0.55kW 0.75kW 1.1kW 2.2kW
4A 8A 8A 8A 16A
Mains input 3 x 400V

7.5kW 11.0kW 15.0kW 22.0kW 30.0kW 37.0kW
35A 35A 63A 63A 80A 100A
12.6.Ventilation
For all inverters, the permissible ambient temperature of 45 °C must not be exceeded. This
particularly applies if the inverter is installed in a control cabinet, because operation of the inverter
may increase the ambient temperature substantially. Appropriate measures, e.g. installation of a
fan, must be taken if the permissible ambient temperature is almost reached or exceeded under
full loading of the inverter.
