➤ For other application conditions, check and determine the supply cross-sections accord‐
ing 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

2.12 Network Conditions
The mains conditions apply to machines connected to public mains supplies with the following
characteristics:
■ Mains frequency: 50Hz
■ Rated voltage between exterior and neutral lines 220V ... 250V
■ Rated voltage between the external lines 380V ... 430V
They do not apply to private power supplies within industrial areas isolated from the public
mains.
The machines listed in the table are intended for operation with a public power supply with a
network impedance at the transfer point (house connection) of maximum Z
max.
[Ohm].
The operator must ensure that the machines are only connected to a network that meets these
requirements. If necessary, ask the local electricity utility for the mains conditions.
