Normal overload=110% torque for a duration of 60 s.2) The 3 values for the maximum cable cross-section are for single core, flexible wire, and flexible wire with sleeve, respectively.3) Applies for dimensioning of frequency converter cooling. If the switching frequency is higher than the default setting, the power losses mayincrease. LCP and typical control card power consumptions are included. For power loss data according to EN 50598–2, refer towww.danfoss.com/vltenergyefficiency.4) Efficiency measured at nominal current. For energy efficiency class see chapter 8.4.1 Ambient Conditions. For part load losses seewww.danfoss.com/vltenergyefficiency.5) Measured using 5 m (16 ft) shielded motor cables at rated load and rated frequency.6) Enclosure sizes A2+A3 can be converted to IP21 using a conversion kit. See also chapters Mechanical mounting and IP21/Type 1 Enclosure kit inthe design guide.7) Enclosure sizes B3+B4 and C3+C4 can be converted to IP21 using a conversion kit. See also chapters Mechanical mounting and IP21/Type 1Enclosure kit in the design guide.8) Enclosure sizes for N75K, N90K are D3h for IP20/Chassis, and D5h for IP54/Type 12.9) Two wires are required.10) Variant not available in IP21.Specifications Operating GuideMG20MD02 Danfoss A/S © 10/2016 All rights reserved. 638 8
