For fuse ratings, see chapter 8.7 Fuses and Circuit Breakers.
1) High overload=150% or 160% torque for a duration of 60 s. Normal overload=110% torque for a duration of 60 s.
2) The 3 values for the maximum cable cross-section are for single core,
exible wire, and exible wire with sleeve, respectively.
3) Applies to 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/#/
4) Eciency measured at nominal current. For energy eciency class, see chapter 8.4 Ambient Conditions. For part load losses, see
drives.danfoss.com/knowledge-center/energy-eciency-directive/#/.
5) Cable cross-section is regarded for copper cables.
