Notes
| 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 |
| 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
