| 2) | - The stated value for the max. power consumption is valid for the adjusted power supply.
- Starting current (rotor blocked): - Part winding (PW) motors: Winding 1 / Winding 1+2
- Delta/Star (Δ/Y) motors: Δ / Y
- Take account of the max. operating current / max. power consumption for designing motor contractors, feed lines, fuses and motor protection switches. Motor contractors: Consumption category AC3. |
| 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. The corresponding uncertainty to the sound power level is KWA = 2,5 dB and to the sound pressure level is KpA = 2,5 dB. The values are valid for 50 Hz with the refrigerant R404A at the standard rating points according to EN 12900. - A-weighted sound power level LWA (re 1 pW), in decibel. To determine the values, measurement methods of the ISO 3740 standard with accuracy class 2 or higher were used .
- A-weighted sound pressure level LpA (re 20 µPa), in decibel. The values are calculated from the sound power level in accordance with ISO 11203: LpA = LWA - Q2 at a distance of d = 1m to the reference box.
