Please take further technical information as well as information about the scope of delivery, accessories and peripheral devices from the PDF data sheet. In cases of doubt the details given in there apply. If nothing to the contrary is quoted then the performance data referred is at an ambient temperature of 20°C.

Please observe the notes on installation and/or the space requirements of our products.

The following voltage and frequency tolerances apply based on EN60034-1:
Voltage +/- 5% for a frequency tolerance at the same time of +/- 2%

Examples to illustrate this: Not permissible, for example. is -5% on the voltage and +2% on the frequency. Permissible, on the other hand, are tolerances of -5% on the voltage and -2% on the frequency.

We reserve the right to make technical changes and correct errors. Illustrations can deviate from the original.
