Introduction

Introduction

Split Configuration for Increased Revenue Protection

The CIU (Customer Interface Unit) is optional. The MCU (Metering & Control Unit) and CIU is linked via Mbus 2 wires communication, galvanically-isolated PLC or RF wireless communication, the communication method is on request.

The CIU is installed within consumer’s home, while MCU is installed in a meter cabinet away from consumers.
