Table 6.11 Mains Supply 3x380–480 V AC Normal and High Overload: MH1, MH2, and MH3 Enclosure
1) NO: Normal overload, 110% for 1 minute. HO: High overload, 160% for 1 minute.
A frequency converter intended for HO requires a corresponding motor rating. For example, Table 6.11 shows that a 1.5 kW motor for HO requires
a P2K2 frequency converter.
2) Maximum cable cross-section is the largest cable cross-section that can be attached to the terminals. Always observe national and local
regulations.
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 50-598-2, refer to
www.danfoss.com/vltenergyefficiency.
4) Efficiency measured at nominal current. For energy efficiency class, see chapter 6.5 Ambient Conditions. For part load losses, see
www.danfoss.com/vltenergyefficiency.
5) Measured using 4 m screened motor cables at rated load and rated frequency.
