Handling and installation

• Do not commission any damaged or destroyed components.
• Prevent any mechanical overloading of the frequency inverter. Do not bend any components and
never change the isolation distances.
• Do not touch any electronic construction elements and contacts. The frequency inverter is
equipped with components which are sensitive to electrostatic energy and can be damaged if
handled improperly. Any use of damaged or destroyed components will endanger the ma-
chine/plant safety and shall be considered as non-compliance with the applicable standards.
• Only install the frequency inverter in a suitable operating environment. The frequency inverter is
exclusively designed for installation in industrial environments.
• If seals are removed from the case, this can result in the warranty becoming null and void.
