2.14.1.1 Network conditions
The network conditions apply to machines connected to public mains supplies with the following
characteristics.
■ Mains frequency: 50 Hz
■ Voltage between exterior and neutral lines 220 V... 250 V
■ Voltage between the exterior lines 380 V... 430 V
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 net‐
work 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 re‐
quirements. If necessary, ask the local electricity company for the value of the network impedance.
