Notes
1) | - 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. |
2) | 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).
