Commissioning the drive for a motor in a hazardous area

Commission the drive according to the requirements and limitations set by the application,
the motor manufacturer's instructions, drive firmware manual, local laws and regulations
and this manual.

Minimum switching frequency


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 chapter
Parameter settings for instructions on how to make the setting.

Target audience

The manual is intended for people who install, start-up, use and service the ATEX-certified
motor thermal protection functions of the drive. Read the manual before working on the
drive. You are expected to know the fundamentals of electricity, wiring, electrical
components, electrical schematic symbols and ATEX/Ex regulations.
