Technical Specifications - ABB RVC Instructions D'installation Et D'utilisation

TESTING
MAN mode: add one step, the power factor (cos ϕ) should improve
indicated by a value which is bigger in the inductive range as before.
AUTO mode: after setting the target cos ϕ, RVC should reach this
value after having switched steps.
