1) | Tolerance (± 10%) relates to the mean value of the voltage range. Other voltages and current types on request All data are based on voltage rms values PW = part winding, motors for part winding starting (no start unloaders required) Designs for Y/D on request |
2) | - The stated value for the max. power consumption is valid for the adjusted power supply. - Starting current (rotor blocked):
|
3) | The maximum permissible working current of the compressor (Imax) must not be exceeded. Take account of the guidelines for use of frequency inverter (see compressor assembly instruction or selection software). |
4) | LP = Low pressure HP = High pressure |
5) | Declared dual-number noise emission values are in accordance with ISO 4871.
