Secular operator $T$ is constructed on the basis of the total $S$-matrix and $T$ is proved to be finite in the adiabatic and ultra-violet sense. This secular operator is reduced to the sum of Feynman diagrams and the contributions of the first and second order of the perturbation theory with respect to the electron interaction are calculated.
