Characteristic 1 Characteristic 2
The characteristic declines device-dependently in this range
(seeunitidentication).
On exceeding a load of 105% the overload integrator starts. When falling below the integrator
counts backwards. If the integrator achieves the overload characteristic that corresponds to
the inverter, the error E.OL is triggered.
