Inverter applications

Inverters involve equipment used on a professional basis, deployed in certain areas of
business and industry - and are not operated in the general public domain.
For an EMC-compliant installation, observe the information provided in the Configuration
manual: EMC installation guideline
60612658).
The Power Modules described here are intended for operation in the first and second
environments. Conditions for operation in the respective environment are subsequently listed.
7.8.1.1

Operation in the second environment

Interference immunity
You do not have to take any additional measures regarding interference immunity.
