DGBFE1309618-05.2012-DGbFEI5| Electrical connection5 Electrical connectionDANGER! High voltage! Risk of electric shock! Only carry out work when theelectrical system is disconnected from the power supply!INFO! Connect the compressor motor in accordance with the circuit diagram(see inside of terminal box).Use suitable cable entry point of the correct protection type(see name plate) for routing cables into the terminal box.Insert the strain reliefs and prevent chafe marks on the cables.Compare the voltage and frequency values with the data for the mainspower supply.Only connect the motor if these values are the same.5.1 Information for contactor and motor contactor selectionAll protection equipment, switching and monitoring devices must comply with the local safety regula-tions and established specifications (e.g. VDE) and regulations as well as the manufacturer’s specifica-tions. Motor protection switch is required! Motor contactors, feed lines, fuses and motor protectionswitches must be rated according to the maximum operating current (see name plate). Set the shortcircuit trigger current at max. 7 times the permissible operating current according to the compressorname plate.5.2 Connection of the driving motorThe compressor is designed with a motor for star-delta circuits.Designation on the name plate Sticker on the terminal box∆ / YStar-delta start-up is only possible on 230 V voltage supply .
