We consider the system $\mathcal{F}_4(a,b,c)$ of differential equationsannihilating Appell's hypergeometric series $F_4(a,b,c;x)$. We find theintegral representations for four linearly independent solutions expressed bythe hypergeometric series $F_4$. By using the intersection forms of twisted(co)homology groups associated with them, we provide the monodromyrepresentation of $\mathcal{F}_4(a,b,c)$ and the twisted period relations forthe fundamental systems of solutions of $\mathcal{F}_4$.
