6 Storage
Store the products in a dry and dust-free room if you do not install them immediately.
Observe the Transport and storage conditions [}18] specified in the technical data.
6.1 Drive controllers
The DC link capacitors can lose their electrical strength due to long storage times and must be reformed before
commissioning.
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.
6.1.1 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.
