Internal EMC filter on ATV12ppppM2
All ATV12ppppM2 drives have a built-in EMC filter. As a result they exhibit leakage current to ground. If the leakage current creates
compatibility problems with your installation (residual current device or other), then you can reduce the leakage current by opening the IT
jumper as shown below. In this configuration EMC compliance is not guaranteed.
