Hidden local gauge invariance in Fateev-Zamolodchikov quantum spin chain is studied in detail in the framework of the quantum inverse scattering method (QISM). It is found that, similar to the case of spin 1/2, this model admits an Abelian U(1) gauge transformation and that the energy spectrum is gauge invariant whereas the eigenvectors are explicitly gauge dependent.
