MIDcounter Installation and User Manual

MIDcounter Installation

The MIDcounter is a certified energy meter that allows you to safely and reliably monitor the consumption of your wallbox during each charging session.

Warning: Do not attempt to install the energy meter if you are not a qualified professional electrician. Such actions can cause serious danger and harm to yourself and others.

Compatibility: Only energy meters provided by Free2move eSolutions S.p.A. are compatible. Installation must be performed by qualified personnel in accordance with local regulations. Refer to local regulations and user and wallbox installer manuals on www.esolutions.free2move.com/document-library/ for more information.

Safety Precaution: Before performing any installation or maintenance on the device, ensure the power supply is switched off.

Installation Steps

1. Place the MIDcounter on the wallbox electrical line, after the RCD and MCB.
2. For three-phase or single-phase electrical connection, refer to the dedicated installation manual included in the MIDcounter package.
3. Feed the Modbus communication cables through the wallbox box sheath. Suggested cable: STP class 5E, 0.5 mm² section.
4. Connect the communication cables from the MIDcounter to the wallbox's RS485 output port "CN12" in the following order: GND to SC, RS485-B to B, RS485-A to A.

Diagram Description: A schematic shows the connection between the Utility Meter, Electrical Panel, MIDcounter, Wallbox, and Loads. The MIDcounter and Wallbox are connected via RS485 communication cables, with specific pin connections indicated.

Diagram Description (MIDcounter and PowerMeter Installation): A similar schematic illustrates the connection when a PowerMeter is also installed. Both the PowerMeter and MIDcounter are connected to the same communication bus, with specific pin connections detailed for each device to the Wallbox's CN12 Port.

5. When powering up the MIDcounter for the first time, press and hold the touchscreen button until the display text blinks. Select the SETTING command and press and hold again to enter the setting menu.
6. Select the COMMUNICATION command (COMM on single-phase meter) and press and hold again to enter the connectivity menu. Configure the following parameters:
   • MIDcounter address: 1
   • Bits per second: 38400 bit/s
   • Parity: Even
   • Stop bit: 1
   • Connection mode: 3L+N “Arithmetic” (required for three-phase MIDcounter only)
7. Press and hold ESC to go back. For three-phase PowerMeter only, select INSTALLATION and press and hold to enter the menu. Configure the connection mode as 3L+N "Arithmetic".
