Electrical connection
WARNING!
Danger to life caused by high leakage currents for an interrupted protective conductor.
The drive components conduct a high leakage current via the protective conductor.
Touching conductive parts when the protective conductor is interrupted can result in
death or serious injury.
Observe the following notes on the connection for machines with frequency converters.
To ensure trouble free operation we recommend the mains supply impedance is less than 1% .
The mains supply impedance is the alternating current resistance in the public supply network.
If the input impedance to the inverter does not coincide with the impedance of the line, reflec-
tions occur, which reduces the power transmission and can lead to a non-linear frequency
response.
WARNING!
The three-phase electrical connection may only be performed by an electrician or under
the guidance and supervision of an electrician.
CAUTION!
Arrange the machine's connection cable in such a way that it will not cause a tripping
hazard.
ATTENTION!
Ensure that all 3 phases (L1, L2, L3) and the ground wire are connected correctly. The
neutral conductor (N) of its power supply is not connected.
ATTENTION!
Observe the rotating field!
Please check that the type of current, voltage and protection fuse correspond to the values
specified. A protective earth ground wire connection must be available.
Mains fuse 10A to 16A
