Under normal operational conditions in NSLS-II the energy of the beam extracted from the Booster and transferred to and injected into the Storage Ring (SR) is 3 GeV. It was determined that for the commissioning purposes energy range of the beam reaching the SR is allowed to be 2 GeV - 3.15 GeV. While the upper limit of the beam energy is defined by the maximum possible settings of Booster dipoles at the top of the ramp, the lower energy limit has to be provided by magnet interlocks. The constraints of time and resources do not allow providing dynamic interlocks of the Booster dipoles for commissioning stage of NSLS-II. In this paper we find a feasible solution for the static interlock of magnets in the Booster to SR transfer line (BSR) which creates a required "energy filter".
