7 General SpecificationsMains supply (L1, L2, L3)Supply voltage 380–480 V ±10%Supply voltage 525–690 V ±10%Mains voltage low/mains drop-out:During low mains voltage or a mains drop-out, the frequency converter continues until the intermediate circuit voltage dropsbelow the minimum stop level. The stop level normally corresponds to 15% below the frequency converter’s lowest rated supplyvoltage. Power-up and full torque cannot be expected at mains voltage lower than 10% below the frequency converter’s lowestrated supply voltage.Supply frequency 50/60 Hz ±5%Maximum imbalance temporary between mains phases 3.0% of rated supply voltageTrue power factor (λ) ≥0.9 nominal at rated loadDisplacement power factor (cosφ) near unity (> 0.98)Switching on input supply L1, L2, L3 (power-ups) maximum once/2 min.Environment according to EN60664-1 overvoltage category III/pollution degree 2The unit is suitable for use on a circuit capable of delivering not more than 100000 RMS symmetrical Amperes, 480/690 Vmaximum.7.1 Motor Output and Motor DataMotor output (U, V, W)Output voltage 0–100% of supply voltageOutput frequency 0–5901) HzSwitching on output unlimitedRamp times 1–3600 s1) Voltage and power-dependent.Torque characteristicsStarting torque (constant torque) maximum 110% for 1 min.1)Starting torque maximum 135% up to 0.5 s1)Overload torque (constant torque) maximum 110% for 1 min.1)1) Percentage relates to the frequency converter's nominal torque.7.2 Ambient ConditionsSurroundingsEnclosure size E IP00, IP21, IP54Enclosure size F IP21, IP54Vibration test 1 gRelative humidity 5% - 95% (IEC 721-3-3; Class 3K3 (non-condensing) during operationAggressive environment (IEC 721-3-3), coated 3C3Test method according to IEC 60068-2-43 H2S 10 daysAmbient temperature (at 60 AVM switching mode)- with derating maximum 55 °C1)- with full output power, typical EFF2 motors maximum 50 °C1)- at full continuous frequency converter output current maximum 45 °C1)1) For more information on derating, see the section on special conditions in the design guide.General Specifications Operating Instructions106 Danfoss A/S © 08/2014 All rights reserved.
