Note:
M12 connectors not included with product.
Input/Output Connectors requires any A-Type M12 connector with 5 position female sockets
Profibus Connectors requires any B-Type M12 connector with 5 position female sockets
If the pump is the last bus device connected to the PROFIBUS cable it must be terminated using terminating resistor
(PROFIBUS standard EN 50170).
