Metz Connect MR-AI8 Modbus RTU

Installation

1. 1Mount the Metz Connect MR-AI8 on a DIN TH35 rail inside the electrical distribution cabinet per IEC 60715.
2. 2Wire the resistance or voltage sensors to the 8 analog input terminals according to the MR-AI8 wiring diagram.
3. 3Set the Modbus address and baud rate (default 9600) using the two rotary switches on the front of the module, or configure them via the Mbus configuration tool.
4. 4Connect the RS-485 Modbus RTU bus wires (A, B, GND) from the MR-AI8 to the ModbusCloud gateway (MCG or MLP series).
