Torque: 1.5 N·m (13 lb·in) 2.2.4 Configure dip switches Configure the dip switches with following steps 2.2.4.1 Phase unbalance protection Choose the pin 1 to enable or disable the phase unbalance protection. When the function is enabled, the protection will limit the phase unbalance to 15 A.
v1.0.3 2.2.4.2 Authorization mode Choose the pin 2 to configure the authorization mode for Bluetooth availability. Configuration Function Configuration Key switch (Default) Function Bluetooth If the pin 2 is set to OFF (left), the key switch has to be turned ON to start a charging session. The Bluetooth authentication is deactivated in this configuration but the app can still connect and be used to configure, monitor and update the wallbox.
v1.0.3 2.2.4.4 Maximum current setting Choose the pin 4-6 to configure the maximum output current ratings. Configuration Max. Current Ratings Configuration Max. Current Ratings 6 A (Default) 16 A 8A 20 A* 10 A 24 A* 12 A 32 A* * Depends on model configuration For AC MAX models with a maximum current of 16 A, the configurations 20 A, 24 A and 32 A limit the maximum output current to 6 A. Note: There are cars that do not start the charging session at 6 A.
v1.0.3 2.2.5 Connect input wire 1. Install the copper wire as described. The section of copper wire connected to terminal shall be reserved enough tolerance to prevent any tension or stress from the external force. Note: Copper wire type: 10 mm , 70ºC. 2. Insert the input wire into the terminal accordingly. The cord end terminal shall be inserted to the end without any deviation. Note: Bottom-fed/rear-fed is available for indoor/outdoor installation with cable gland. 3.

v1.0.3 Single phase Three phase IT IT Note: To fulfill requirements for electrical installations in UK, the following shall be observed. 1. When installed in a TN systems, the supplying circuit shall not include a PEN conductor(combined protective and neutral) . 2. If the power grid belongs to TN-C-S system, the charger needs to be grounded separately to TT system. A PME earthing facility shall not be used as the means for the protective conductor contact of a charging point located outdoors. 2.2.
v1.0.3 2. Remove the water proof cap and pass through the signal cable with appropriate conduit or cable gland. 3. Connect the signal cable according to pin definition (2.2.6.1) and must connect to the Pin 1 (+5V). Note: suggested wire of signal cable: 1.5 mm2 . 4. Assemble the connector 5.
v1.0.3 2.2.6.1 Pin definition User can connect the external component with signal cable based on following configuration.
