The connection to an IT three-phase supply or a three-phase supply with one earthed phase is not
permitted.
Further information When connecting to a European 400V/3/50Hz rated voltage the requirements in chapter 2.12 are
also to be observed.
2.11.1.1 Power supply specifications
The following supply cable conductor cross sections and fusing (slow-blow class gG) are selected
according to German DIN VDE 0100 Part 430 (IEC 60364-4-43) and DIN VDE 0298-4:2013-06
standards for these conditions:
■ Multi-core copper conductors at an operating temperature up to 70 °C
■ Cable length <50 m
■ for 30 °C ambient temperature
■ wiring type C: without cable contact
■ Current carrying capacity: Table 3, column 11
(European Harmonisation Directive HD 60364-5-52:2011)
■ Bundled cables: Table 21,
─ Single layer on wall or floor
─ Spacing ≥ outside diameter
➤ For other application conditions, check and determine the supply diameters according to
DIN VDE 0100 and DIN VDE 0298-4:2013-06 or the local energy provider.
Other application conditions would include, for example:
■ Higher ambient temperature
■ Other cable installation method
■ Other cable bundling
■ Cable length >50 m
Mains frequency: 50Hz
Rated voltage: 230V±10% / 3 / 50Hz
