  25. General Technical Basis: Power, Climate, Compressed Air
    1. The equipment is designed for following electrical characteristics: power supply 3 x 380 (400) V, AC, PE and loadable neutral line.
    2. Control voltage: 24 V DC.
    3. Frequency: 50 (60) Hz.
    4. Voltage variation: maximum ± 10%.
    5. Frequency variation: ± 2 CPS.
    6. 3 x 415 V AC, PE and loadable neutral line.
    7. Control voltage: 24 V DC.
    8. Frequency: 50 (60) Hz.
    9. Voltage variation: maximum +5% -10%.
    10. Frequency variation: ± 2 CPS.
    11. The equipment is not trop-proofed and is designed for operation below 1,000 m above sea level. Higher altitudes lead to load reduction.
    12. Ambient and cooling air temperature for static inverters and operator stations have to be stable and a maximum of 35 °C should not be exceeded. Depending on the equipment and the rate of utilization this value has to be slightly corrected.
    13. The relative humidity must be less than 85%.
    14. The equipment is designed for compressed air connection at a constant operating pressure of 6 bar. If the limit value of 8 bar pressure is exceeded in customer’s plant, reduction valves have to be provided by customer.
  26. Standards
    1. The equipment, including the pressure vessels has been designed, manufactured and tested according to the applicable German and European standards (VDE, EN, IEC).
    2. Protection class for inverters, control cabinet and operator stations is as a minimum IP33 according to VDE 0470-Part 1 (=EN 60529 = IEC 529), which means that the components are protected against solid particles of 2.5 mm diameter as well as against spray water.
    3. Protection class of motors is IP23 according to VDE 0530-Part 5 (=EN 60034-Part 5 = IEC 34-Part 5). This covers protection against solid particles of 12.5 mm diameter as well as against spray water.
    4. The electronics are designed in accordance with the European standard EN 60721-3-3 / climatic environmental conditions class 3K3. This means particularly that no moisture is allowed on the electronic components during operation. This requirement also applies to the shutdown and start-up conditions of the air conditioning system.
