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
The system integrator is responsible for the compliance of the complete motor thermal
protection circuit with the European ATEX Product Directive 2014/34/EU. If the compliance
of the system with the ATEX Product Directive requires the motor thermal protection, make
sure that the:
• drive/inverter module is equipped with the ATEX-certified Safe disconnection function
(option +Q971)
• motor thermal protection relay is ATEX-compliant
• motor thermal protection circuit is wired according to the instructions given in this
guide and in the motor manual and according to the installation requirements of the
relevant standard(s) of EN/IEC 60079 series.
