For maintenance or to open the switchboard cabinet, it is essential to make a measure-
ment to ensure there is no voltage!

6.3.1 Automatic powering on

When there is a grid disturbance or an unusual mains voltage or frequency, the SVG
powers off automatically, thereby terminating the control. Once the following conditions are
fulfilled, the SVG restarts automatically.
1. The power grid has been reestablished
2. The auto-restart function is activated
3. The auto-restart delay time has expired (default setting: 10s)
If the auto-restart function has not been set in the SVG, the user must restart the SVG
manually via the monitor screen.
