Notes
1) | Value calculated. Deviation to reality possible. |
2) | 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)

3) | - 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. |
4) | 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).

5) | LP = Low
pressure HP = High pressure |
6) | 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.
