IRC5C with Keyence GC-1000 CIP Safety Setup

We just purchased our first robot and we're trying to setup the safety circuit.  We haven't done this before and have very limited knowledge of ethernet/IP so I realize we might need to contract with an integrator but would like to start on our own.  Reading through the manuals, I'm having a difficult time figuring out how to configure the IRC5C to communicate with our Keyence GC-1000 safety controller.  Does anyone know of a document that might help a novice walk through this process?  Thanks!
