Changing The Response Threshold Of The Braking Transistor - KEB Combivert F5 Installationsanleitung

Annex A
Storage period > 3 years
• Input voltages as before, however double the times per year. Eventually change
capacitors. Eventually change capacitors.
After expiration of this start-up the KEB COMBIVERT can be operated on nominal rating
conditions or delivered to a new storage.
