5.1 Drive controller
The DC link capacitors can lose their electrical strength due to long storage times.
ATTENTION!
Material damage due to reduced electrical strength!
Reduced electrical strength can cause considerable material damage when switching on the
drive controller.
▪ Reform drive controllers in storage annually or before commissioning.
5.1.1 Annual reforming
To prevent damage to stored drive controllers, STOBER recommends connecting stored
devices to the supply voltage once per year for one hour.
The following graphics show the basic line connection for 3-phase devices.
