KEB COMBIVERT F5 Series - Changing the Response Threshold of the Braking Transistor

GB - 29
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.
A.5 Changing the response threshold of the braking transistor
(not valid for control type „BASIC“)
To prevent a premature switching of the brake transistor at input rated voltage of 480 Vac,
the response threshold must be adjusted according to the following diagram.
