We study a local system associated with a systemof hypergeometric differential equations in two variables of rankwith seven parametersand. We modify the fundamental system of solutions togiven in [A system of hypergeometric differential equations in two variables of rank 9,Internat. J. Math.28(2017), 1750015, 34 pp] so that it is valid even in cases wheresatisfy some integral conditions. By using this fundamental system, we show the irreducibility of the monodromy representation ofunder some conditions on the parameters. We characterize the fundamental group of the base space of this local system as the group generated by three loops with four relations among them.
