Energy meter
Supported energy meter:
EVHEM217 (Carlo Gavazzi EM2172RVV23XOSX)

• Connect the energy meter to terminals 1 [B+], 2 [A-] and 3 [GND].

• Use a twisted pair instrumentation cable RS-485 when you connect the energy meter to the charging station.

• Recommended cable type: NESMAK-HF 2x2x0,5+0,5 or similar.

• The system has been tested with 100 m cable length.

• Make sure that the RS-485 baud rate is equal in the charging station and the energy meter.

• Do not change EVHEM217 Modbus default parameters.
  Modbus: client ID 1
  Databits: 8
  Parity: none
  Stopbits: 1

• Make sure that the signal wires are connected correctly to the energy meter.

• Terminate the transmission line in accordance with the wiring example on the next page. Please see the energy meter instructions for more detailed information.

External control device

6.2.1. Dynamic Load Management (DLM)
You can implement dynamic load management with for this purpose compatible energy meter. The figure below shows an example how you can build up the system.

• The energy meter measures the total power consumption and the actual current per phase. If some other load over the set maximum current for load management is added when charging is ongoing, the charger will decrease the charging current. If the total power consumption reaches the allowed maximum power, the charging interrupts untill the the total power consumption has decreased to a value at which the charging can continue.
• Use only current transformers which have the same serial number, they are calibrated with one another.
• 1-phase measurement: select the correct parameters in the energy meter’s settings.
• Please see the energy meter instructions for more detailed information.

6.2.2. Load Management in Override mode
Ensto One charging stations are compatible with a variety of home control systems.
The Legrand group has a wide assortment of devices for home control systems. The figure below shows an example how you can build up load management with Netatmo Connect.

• If the total load reaches the allowed maximum power, the Smart Load Shedder sends a signal to the Connected Contactor. The Connected Contactor switches off the charging current. When the Connected Contactor gets a signal that the total power consumption has decreased to a set value, it switches on the charging current.

This installation requires a “with Netatmo” connected starter pack or a Gateway module.

Please ask our local sales representative detailed information about the required devices for your installation.

6.2.3. Control of charging in Override mode
The charging events can be controlled by a dry contact module. The figure below shows an example how you can build up the override control of charging with a timer, switch, relay or similar.
When the dry contact is closed, the charging station gets power and can charge the connected vehicle.
When the dry contact is open, the charging station does not get power and charging is not possible.
