The CIM 200 solution is an add-on communication module to be installed internally in a Grundfos E-pump (11-22 kW) or MAGNA3 pump, using a 10-pin connection. In this setup, the E-pump will supply power to the CIM 200.
The CIU 200 solution is a box with a power supply module and a CIM 200 Modbus module. It can either be mounted on a DIN rail or on a wall.
