1.8 Intended use
The devices of the DS7 series
• are not devices for household use, and are designed exclusively for use
in commercial applications,
• can be used in the described system configurations in the industrial
environment,
• are not machines in the sense of the EC Machinery Safety Directive,
• comply in a typical drive configuration with the requirements of the EU
EMC Directive, the EU Low Voltage Directive, as well as the specified
standards.
The soft starters of the DS7 series are electrical apparatus for installation in
the control panels of electrical systems or machines. They are designed for
the soft starting of single-phase or three-phase AC motors mounted in a
machine or for assembly with other machine or plant components.
