    PRODUCT OVERVIEW This manual applies to Wall Connectors identified by part number 1457768-**-*. Product Specifications Voltage and Wiring Nominal 200-240 V AC single-phase Current Output Range 12 – 48 amps Terminal Blocks 12-4 AWG (3.5 - 25 mm ), copper only ¾...

  • Page 6: Circuit Breaker Rating / Maximum Output

    Commissioning Procedure on page 28 for details. NOTE: Some Tesla vehicles may draw less current than the max output. Actual charging rate depends on Wall Connector output and onboard charger in the vehicle. Branch Circuit Conductors and Ground Wire • If installing for less than maximum power, refer to local electrical code to select correct conductors and ground wire size that are suitable for the chosen circuit breaker.

  • Page 7: Using Wall Connector

    PRODUCT OVERVIEW Grounding Connections Wall Connector must have a ground path back to the main equipment earthing point on site. Without a proper ground connection, the Wall Connector will fault during a ground assurance test. Equipment- grounding conductor must be run with the circuit conductors and connected to the equipment-grounding terminal in the wirebox.

  • Page 9: Features

    Connectivity Wall Connector is equipped with Wi-Fi to communicate with local site routers, vehicles, mobile devices, other Wall Connectors, and other Tesla products. Hosted Access Point Wall Connector hosts a WPA2 password-secured, 2.4 GHz, 802.11 Wi-Fi access point network to facilitate commissioning and connecting to other devices.

  • Page 10: Ground Fault Circuit Interruption

    PRODUCT OVERVIEW Ground Fault Circuit Interruption Integrated ground fault circuit interruption (GFCI) protection automatically detects a current mismatch between power delivery conductors that would indicate that current is flowing through the ground (PE) conductor. If a ground fault occurs after 10 seconds of charging, Wall Connector will wait 15 minutes before automatically re-attempting to charge.

  • Page 26: Power Sharing

    POWER SHARING Power Sharing Overview The firmware-based power sharing feature enables up to 6 Wall Connectors installed at the same site to intelligently share the site's total available power via unit-to-unit Wi-Fi. This minimizes the need for many residential and commercial applications to have specific electrical upgrades for concurrent multi-vehicle charging.

  • Page 27: Breaker And Branch Circuit Setup

    POWER SHARING Breaker and Branch Circuit Setup Power sharing circuits may be installed in an electrical panel that supports other loads. If space is limited or the main power supply is far from the Wall Connectors, installing a dedicated load center may be prudent. See below for examples of Wall Connector power sharing diagrams (one with sub-panel and one without).

  • Page 28: Considerations For Power Sharing

    POWER SHARING Considerations for Power Sharing Wall Connector power sharing is achieved wirelessly. For optimal performance, Wall Connectors within a power sharing network should be installed within view of each other whenever possible. NOTE: Line of sight is recommended but not required. Wireless communication is capable of reaching around concrete corners but network range may degrade as a result.

  • Page 29: Power Sharing Commissioning Procedure

    POWER SHARING Power Sharing Commissioning Procedure 1. Identify and configure the wall connector. One Wall Connector will be the designated leader and provide the configuration and controls for all followers. Install and configure the leader first. Follow the process in the Commissioning Procedure on page 28 to connect and configure the leader.
  • Page 30 POWER SHARING NOTE: In the event that your leader and followers have different circuit breakers, you have to individually connect to each of the followers on different breakers via the Wi-Fi broadcast, and then set the correct breaker limit. NOTE: For example, in a four Wall Connector network with two 60 amp breakers, one 50 amp breaker and one 20 amp breaker where the leader has a 60 amp breaker, individually connect to the Wall Connectors with 50 amp and 20 amp breakers and set their current limit in the commissioning interface using the...
