Optional Energy Management Settings

In the ChargePoint Installer App, Energy Management settings are available only if the charger is being commissioned as a home charger.

ChargePointFlex Pro charging station supports the following energy management solutions:

  1. Shunt Trip

  2. Current Dial

  3. Smart Meter

  4. Ethernet

  5. J1/J2 Jumpers

  6. Current Transformers

Shunt Trip Wire

If local regulations require that the charging station be connected to an RCDClosed Residual Current Device with shunt trip capability, use a 4.5 mm flat blade screwdriver to connect the shunt trip wire.

Shunt Trip Wiring Labels

Label

Meaning

Notes

L1

L1 connection to shunt trip

Connect to external shunt trip line connection if shunt trip action is required on detection of DC leakage fault

N

Neutral connection to shunt trip

Connect to external shunt trip Neutral if shunt trip action is required on detection of DC leakage fault

  • Shunt trip must be rated to 230 VAC (L-N) - do not use DC input shunt trip.

  • Use wire strippers to remove 6-7 mm of wire insulation for installation into back plate shunt trip connector.

  • Acceptable wire sizes are 0.5-2.5 mm2

Smart Meter Functionality

Local regulations may require smart meter functionality. The RJ12 connector is dedicated for smart metering functions. Determine your smart meter type and adjust J1 and J2 jumpers accordingly.

After connecting your smart meter to the RJ12 socket, configure load management settings in the ChargePoint Installer app.

TCP/IP meters should be plugged into the same Local Area Network (LANClosed Local Area Network) as the ChargePoint charging station. Note the IP address so you'll have it handy when you configure this detail in the ChargePoint Installer app.

Supported models appear below:

Supported Models

Meter

Connection Method

Siemens PAC2200

MODBUS TCP via Ethernet RJ45 Port

Ethernet

Ethernet can be used to connect the charging station to a supported smart meter via MODBUS TCP/IP using an Ethernet RJ45 port. Ensure the meter is plugged into the same Local Area Network (LANClosed Local Area Network) as the charging station and note the meter’s IP address for configuration. For correct operation of Dynamic Load Management (DLMClosed Dynamic Load Management), configure the connection and settings in the ChargePointInstaller app.

Current Transformers (CT)

Local regulations may require that you connect one or more CTs. The CT has a directional arrow in the middle of the core. This should be installed on the conductor pointing in the same directional flow of the current. Use the ChargePoint Installer app to configure load management settings.

Use the included connector to connect external CTs.

CTs are pre-wired into an 8-pin plug. Insert the plug into the CT connector shown below.

  1. CT socket with pin orientation

  2. CT connector at the end of the cable with pin orientation

CT Pin Configuration

Connection

1

CT1 Negative
2 CT1 Positive
3 CT2 Negative
4 CT2 Positive
5 CT3 Negative
6 CT3 Positive

The expected configuration is CTs with a current of 100 A and output voltage of 333 mV (burden resistor included).

For correct operation of DLMClosed Dynamic Load Management (Dynamic Load Management), use the ChargePoint Installer app to configure the station.
