2 Safety
2.1 Safety
When designing AC drives, some residual dangers cannot be avoided constructively. One example is the discharge time, which is
very important to observe to avoid potential death or serious injury. For the Danfoss VLT® drives, the discharge time is from 4–40
minutes depending on the drive size.
For further information on safety precautions, refer to the product-specic Operating Guide.
