Connecting explosion-protected AC motors

Observe the following information:

• Install the inverter outside the potentially explosive atmosphere.
• Observe industry and country-specific regulations.
• Observe the regulations and information of the motor manufacturer with regard to operation on a frequency inverter, e.g. mandatory sine filter.
• All operating resources used in potentially explosive atmospheres must adhere to the relevant standards, such as Directive 2014/34/EU or IEC 60079.
• In connection with the HV brake control /B, the brake control must be set to "voltage control" because choppers in the brake coil is not permitted.
• The sensor input of the motor's temperature monitoring must not be used in potentially explosive atmospheres. For thermal monitoring, use a monitoring device approved for potentially explosive atmospheres.
• In case of motors with speed feedback, the speed sensor must also be approved for potentially explosive atmospheres. The speed sensor can be directly connected to the inverter.
