2�4 Requirements of electrical power
List of the most using and prewired voltage:
Motor
4 kW (5.5 HP)
Voltage
380 V
Phase
3 Ph
Frequency
50 Hz
Nominal current
8.3 A
Prewired
380 V / 3 Ph
Cords
5
The steady-state AC power supply is 0.9 ~ 1.1 times of the rated value.
Frequency
0.99 ~ 1.01 times of rated frequency ( 50 Hz , continuous working)
0.98 ~ 1.02 times of rated frequency(50 Hz, short period working)
Harmonics
The sum of 2nd - 5th distorted harmonic must not exceed 10% of RMS of voltage. An additional 2% of RMS of line voltage is
allowed to for the sum of 6th - 30th harmonic.
Unbalanced voltage
Neither Negative nor zero sequence components is allowed to exceed 2% of the positive sequence component.
Electrical protection
End user should provide protection device against overvoltage due to lightning and short-circuited protection device at the
power supply.
Ingress Protection at the inlet of incoming power cable
The incoming method of incoming cable should ensure IP54 protection class when finishing installation on the spot.
2�5 Noise
Reference standards
The measurements of noise emission were conducted according to the EN ISO 11202 for the determination of sound pressure
level at the operation positions. When the measured sound pressure levels at the operation positions exceed 85 dB(A), the
measurements of sound power levels were conducted according to EN ISO 3746.
Operating conditions
The operating conditions for noise measurement comply with Annex A of ISO 7960:1995.
