700S and 700H Frame 14 Replacement Power Structures Introduction Important: The Power Modules on PowerFlex 700S Phase II and 700H frame 14 drives are matched at the factory and cannot be paired with any other Power Modules. Therefore, when a Power Module fails, you must replace both power structures on a frame 14 drive.
