The Communication Interface Module (CIM) is an add-on communication module you install internally in a Grundfos E-pump using a 10-pin connection. In this setup, the E-pump will supply power to CIM 200. See fig. 1.For mounting of the CIM add-on module, see the installation and operating instructions for the E-pump in question.CIU solutionThe Communication Interface Unit (CIU) is a box with a power supply module and a CIM Modbus module. You can mount either on a DIN rail or on a wall.You use it in conjunction with Grundfos E-pumps that do not support an internal, add-on communication module, CIM.
