Power Supply
Power Supply Basic requirements The machine is designed for a power supply conforming to EN 60204–1 (IEC 60204–1), section 4.3. In the absence of other user-specified conditions, the limits laid down in this standard must be adhered to. It is recommended that the supplier and user confer and agree on the basis of the EN 60240–1, Annex B. The machine requires a symmetrical three-phase power supply. In a symmetrical three-phase supply the phase angles and voltages are all the same. The machine may only be operated from an earthed TN or TT three-phase supply. Connection to an IT supply is not permitted without taking further measures (earth leak detection, etc.). Further requirements Demands on a three-phase supply for a machine with the following equipment: ■
Variable frequency drive (SFC)
■
Refrigeration dryer powered from a transformer
This machine may only be supplied from an earthed TN or TT three-phase supply in which the neutral point is earthed. The machine may not be connected to a three-phase supply in which one of the phases is earthed, as this can lead to dangerous voltage surges. Connection to an IT supply is not permitted without further measures being taken (earth leak detection, specially designed frequency converter, etc.). Further information
2.14
The electrical diagram in chapter 13.4 contains further details of the power supply connection.
Power Supply Specifications The following supply cable conductor cross sections (copper multicore) and fusing (slow-blow class gL) are selected according to German DIN VDE 0100–430 (IEC 60364–4–43 and IEC 60364– 4–473) and DIN VDE 0298-4 standards for 30 °C ambient temperature and wiring type C. ➤ The conductor cross-sections should be changed accordingly if other conditions prevail. Other conditions would include:

Cooler specification (option K2)
Cooling water quality Oil may contaminate the cooling water if a leak occurs. ➤ A special heat exchanger must be used for heating drinking water. The specific heat capacity and required flow rate of the cooling water changes if antifreeze is added. ➤ Consult KAESER Service to ensure optimum cooling-system performance. It is imperative that measures for cooling water treatment and filtration are implemented. KAESER can provide the names of companies specializing in cooling water analysis and the supply of suitable treatment plant. Characteristics/content
