Commissioning the drive for a motor in a hazardous area
Commission the drive according to the requirements and limitations set by the application,
the instructions of the motor manufacturer, drive firmware manual and local laws and
regulations.
The certificate of the Ex motor typically requires that you set a minimum limit for the output
switching frequency of the drive. Make sure that the Ex motor is operated above the
minimum output switching frequency specified by the motor manufacturer. See section
Switching frequency limitation on page 23 for instructions on how to make the setting.
Compliance with the European ATEX Product
Directive 2014/34/EU
