Conversions or changes carried out on or in the inverter and its components and accessories without express authority render all warranty claims null and void. Please contact BERGES if any conversions or changes are necessary, particularly in relation to the electric components.

BERGES electronic The components of the power section and specific elements of the control section are connected to the voltage mains when the inverter is connected to the mains voltage. Touching these components involves mortal danger! Isolate the inverter from the mains before removing the front panel or the housing (e.g. by removing or deactivating on-site fuses or by deactivating a master switch isolating all poles etc.).
Only personnel informed about the functions and hazards of the inverter may be employed for the purposes of operation, maintenance and repair. Only items expressly approved by BERGES (e.g. mains filters and chokes etc.) may be used as accessories. The installer of the system is liable for any damage resulting from the use of accessories that have not been approved expressly by BERGES.

BERGES electronic 11. Installation examples 11.1. Exemple 1: ACM-D2 0.37 kW - 2.2 kW (1 x 230V) 1) The GND terminals (10, 12 and 14) are floating and serve, among other things, as the reference potential for shielded cables of the control inputs. This potential must be grounded directly either at the control side (PLC or similar) or at the inverter (PE to one of the terminals 10, 12 or 14).
BERGES electronic 11.2. Exemple 2: ACM-D2 0.75 kW - 30 kW (3 x 400V) 1) The GND terminals (10, 12 and 14) are floating and serve, among other things, as the reference potential for shielded cables of the control inputs. This potential must be grounded directly either at the control side (PLC or similar) or at the inverter (PE to one of the terminals 10, 12 or 14).
−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 insufficient if the unit is installed in a control cabinet with a small volume.
BERGES electronic Frequency inverters must not be connected via a residual-current-operated circuit- breaker as the sole protective measure! The single exception below permits connection of a frequency inverter via a residual-cur- rent-operated circuit-breaker as the sole protective measure: Installation of a residual-current-operated circuit-breaker of the newest design for frequency in- verters up to 4kVA (input voltage 1x230V) with MOBILE connection.This residual-current-...
Other measures may be necessary to reduce or suppress interference if the mains voltage is ‘‘contaminated’’. No generally valid recommendations can be given in such cases. Please consult BERGES if all recommended interference suppression measures should not produce the desired result.
BERGES electronic Other loads connected to the mains may produce voltage spikes that may interfere with functioning of the inverter or may even damage it. Chokes or main filters can be used on the mains side to protect the inverter against voltage spikes (resulting from switching large loads to the mains, for example).
BERGES electronic 12.6. Series autotransformer A series autotransformer is dimensioned as follows (guide value): Rated inverter output × 2 = Transformer output in kVA. Attention must be paid to the voltage increases in no-load condition when using isolating transformers. 12.7. Ventilation For all inverters, the permissible ambient temperature of 45 °C must not be exceeded.
BERGES electronic 13. Commissioning and settings 13.1. General information The following points must be observed before commissioning: • Corresponding of the mains voltage with the input voltage of the inverter. • Check that the motor has the correct type of connection (star-delta connection).
BERGES electronic 14. Operating functions 14.1. General The ACM-D2 inverters are pre-programmed to run a 4-pole AC-induction motor. In many cases no additional programming is required. 14.2. Control panel All functions of the inverter can be controlled by way of the ACM-D2 control panel. The 4 input keys allow control of the motor and direct parameter programming.
BERGES electronic 14.3. Display An eight-position alphanumeric display provides the user with all important information, such as inverter status messages and information on possible errors or faults and parameter setting values.The language for the display readout is selectable. 14.4. Help - function and language - select When pressing SHIFT and INC, on the display appears a scrolling Help-text concerning the currently active function.
