	Modern Energy Recovery Linac (ERL) projects use superconductive accelerating radio-frequency structures (RF). Their RF quality is typically very high. Therefore, the RF voltage induced by electron beam is also high. In ERL the RF voltage induced by the accelerating beam is almost cancelled by the RF voltage induced by the decelerating beam. But, a small variation of the RF voltage may cause the deviations of the accelerating phases. These deviations then may cause further voltage variation. Thus, the system may be unstable. The stability conditions for ERL with one accelerating structure are well known. The ERL with split RF structure was discussed recently. The stability conditions for such ERLs are discussed in this paper
