1) Applies for dimensioning of frequency converter cooling. If the switching frequency is higher than the default setting, the power losses may

increase. LCP and typical control card power consumptions are included. For power loss data according to EN 50598-2, refer to

drives.danfoss.com/knowledge-center/energy-eciency-directive/#/.

2) Eciency measured at nominal current. For energy eciency class, see chapter 8.4.12 Ambient Conditions. For part load losses, see
