PRODUCT OVERVIEW Circuit Breaker Rating / Maximum Output Power Output For maximum power output, install a standard double pole 60 amp circuit breaker. Wall Connector includes integrated GFCI protection - do not install a GFCI circuit breaker. Wall Connector incorporates automatic load management, which allows the max output to be customized to an existing power supply. If the electrical supply is unable to support the 60 amp configuration, select a lower amperage configuration. Circuit breaker (amps) Max output (amps) Power output at 240 volts (kW) 60 48 11.5 50 40 9.6 40 32 7.6 30 24 5.7 20 16 3.8 15 12 2.8 NOTE: External disconnect switches are neither required nor recommended. NOTE: Circuit breaker size is programmed during the commissioning process. See Commissioning Procedure on page 22 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. • If installing for maximum power, use minimum 6 AWG, 90° C-rated copper wire for conductors. NOTE: Upsize conductors if necessary. • For sites with multiple Wall Connectors, each Wall Connector must have its own branch circuit with L1, L2/N, and Ground. • COPPER WIRE TERMINATIONS ONLY for landing in Wall Connector wirebox terminals. Conductors can be stranded or solid. • For outdoor installations, use watertight fittings when securing feeder wires to the wirebox. Grounding Connections Wall Connector must have a ground path back to the main equipment earthing point on site. Without a oper ground connection, the Wall Connector will fault during a ground assurance test. Equipment- pr grounding conductor must be run with the circuit conductors and connected to the equipment- grounding terminal in the wirebox. Install a ground (PE) wire sized according to local electrical code. Gen 3 Wall Connector Manual 5

PRODUCT OVERVIEW 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. A unique SSID Wi-Fi network name and WPA2 password for connecting to the Wall Connector are printed on a label at the rear of the main unit, as well as on the front cover of the Quickstart Guide included in the box. Local Network Connecting Wall Connector to a local Wi-Fi network enables it to receive over-the-air firmware updates, remote diagnostics access, and usage data tracking capability. Wall Connector only supports WPA2/3-secured, 2.4 GHz, 802.11 infrastructure mode networks. NOTE: Hidden networks are supported. NOTE: WPA enterprise will be supported in a future firmware update. Gen 3 Wall Connector Manual 7

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. Up to four attempts to charge will be made before user interaction is required. If a residual current fault occurs within 10 seconds of charging, Wall Connector will lock out and user interaction is required to restore charging functionality. Recommended interaction includes pressing the button on the charging handle, or removing the charging handle from the vehicle and reinserting it. If this does not resolve the issue, look for a ground fault issue such as water ingress. Ground Assurance Wall Connector continuously checks for the presence of a safe ground connection and automatically recovers from faults. Ground assurance operates by injecting a small amount of current into the ground conductor in order to measure the impedance between line and ground. If high impedance is detected, the Wall Connector will lock out charging and display a fault code of two (2) red blinks. See Fault Codes on page 27 for a full list of fault codes. One leg of the distribution transformer must be ground-bonded (Neutral) for the ground assurance detection to function properly. Residential power supplies typically bond ground to neutral at the main electrical panel, while commercial sites must provide a ground bond at the transformer. Ground bond should only occur at one location in a site's electrical system. Wall Connector ground assurance does not support an IT grid configuration. Temporary problems such as ground faults or utility power surges are resolved automatically. Power Outages If there is a power outage while Wall Connector is charging a vehicle, charging will automatically resume within 1 to 3 minutes after power restoration. The Wall Connector will display a solid blue light on the faceplate to indicate that it is communicating with the vehicle and waiting to resume charging. Alternatively, pressing the button on the charging handle after power restoration will cause Wall Connector to resume charging immediately. Firmware Updates Firmware updates will be automatically applied to the Wall Connector to improve the user experience and introduce new features. Connect Wall Connector to Wi-Fi for access to the most recent firmware update. See Commissioning Procedure on page 22. Tesla vehicles can provide firmware updates to Wall Connectors. 8 Gen 3 Wall Connector Manual

Gen 3 Wall Connector Manual 21

COMMISSIONING PROCEDURE The commissioning process for Wall Connector enables easy configuration of circuit breaker size, Wi-Fi connectivity, and power sharing options. 1. Turn on Wall Connector's corresponding branch breaker to energize the unit. On startup, Wall Connector will display green LEDs for 10 seconds to indicate the maximum circuit breaker it is configured for. 2. Use a Wi-Fi-enabled device such as a smart phone to connect to the SSID Wi-Fi signal broadcasted by the Wall Connector. Joining the Wall Connector network can be done by scanning the sticker QR code on the Quickstart Guide cover page, or by manually selecting the network and typing in the WPA2 password (found on the sticker on the Quickstart Guide cover page). NOTE: The Wi-Fi network will only broadcast for 5 minutes. To have the Wall Connector broadcast the SSID again, hold the button on the charging handle for 5 seconds or turn the circuit breaker off, then on again. NOTE: If you are unable to connect to the Wall Connector SSID, turn off the cellular data on your mobile device and try again. 3. Scan the QR code below with the device that is connected to the Wall Connector to access the web browser commissioning interface. Alternatively, manually type the URL address (http://192.168.92.1) into the web browser. 4. Follow the onscreen commissioning steps on the web browser to assign Wall Connector to its own circuit breaker and connect it to the local site Wi-Fi network. 22 Gen 3 Wall Connector Manual

POWER SHARING Power Sharing Overview This feature will be available in a future over-the-air firmware update. The firmware-based power sharing feature enables up to 16 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. During the commissioning process, • Wall Connectors are allocated to individual branch circuits (each up to 60 amps) • Total power is allocated to the group of linked Wall Connectors Total current output of Wall Connectors that share power will never exceed the site's total allocated power. 1. AC feed (service panel) 2. Power sharing via Wi-Fi communication Gen 3 Wall Connector Manual 23

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). Each individual Wall Connector in below examples is capable of providing 48 amps when it is the only one in use. As more Wall Connectors begin plugging into vehicles, the system will automatically distribute power based on the total power allocated to the site. Power Sharing Setup with Sub-Panel 1. Wall Connector 2. 60 A branch circuit 3. 100 A sub-panel / feeder breaker Power Sharing Setup Without Sub-Panel 1. Wall Connector 2. 60 A branch circuit 24 Gen 3 Wall Connector Manual

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. Avoid placing Wall Connectors on opposite sides of concrete, masonry, metal studs, and other physical obstructions that would impede Wi-Fi signal strength. NOTE: If a mobile device is able to connect to local Wi-Fi, it is a good indication that the Wall Connector will also be able to connect. Calculating Power Sharing Requirements for Existing Systems To calculate power supply requirements per number of Wall Connectors for existing electrical systems, use the following equation: Available continuous Number of Wall Connectors: Max amperage output per Wall Connector amperage: when 100% utilized: _____________________ ÷ ________________________ = ________________________ NOTE: Maximum number of Wall Connectors for power sharing is 16. NOTE: When calculating maximum amperage per Wall Connector, 100% utilization must be greater than 6 amps for power sharing operation. If maximum amperage is greater than 48 amps, power sharing is not necessary. For large scale sites, consider expected parking time in relation to a 100% utilization rate. Expected Park Time (hours) Examples Recommended Amperage per wall Connector at 100% Utilization 6+ (long term) Long term parking, overnight 12+ amps parking 3-5 (medium term) Workplace, hospitality 24+ amps 1-2 (short term) Shopping and dining 32+ amps NOTE: 100% utilization represents the worst case scenario for charging speeds, where the least amount of power would be available for each individual vehicle. In most situations, not all Wall Connectors would be actively charging a vehicle, which enables faster charging for the remaining vehicles. Gen 3 Wall Connector Manual 25

WALL CONNECTOR LEDS Light Codes Startup Once energized at the circuit breaker, every LED (seven total) on the faceplate will illuminate for one second.

Under no circumstances will the original warranty period be extended as a result of your Tesla connector or adapter being repaired or replaced. Tesla shall not be liable for any defects under this Charging Equipment Limited Warranty that exceed the fair market value of the applicable Tesla connector or adapter at the time immediately preceding the discovery of the defect. In addition, the sum of all benefits payable under this Charging Equipment Limited Warranty shall not exceed the price you paid for the applicable Tesla connector or adapter. Tesla does not authorize any person or entity to create for it any other obligations or liability in connection with this Charging Equipment Limited Warranty. Subject to local laws and regulations, the decision of whether to repair or replace a part or to use a new, reconditioned or remanufactured part will be made by Tesla, in its sole discretion. Tesla may occasionally offer to pay some or all of the cost of certain repairs that are not covered by this Charging Equipment Limited Warranty, either for specific models or on an ad hoc, case-by-case basis. Tesla reserves the right to do the above at any time without incurring any obligation to make a similar payment to other Tesla charging equipment owners. To the maximum extent permissible under local law, Tesla hereby disclaims any and all indirect, incidental, special and consequential damages arising out of, or relating to, the Tesla connector or adapter, including, but not limited to, transportation to and from a Tesla Authorized Service Center, loss of the Tesla connector or adapter, loss of vehicle value, loss of time, loss of income, loss of use, loss of personal or commercial property, inconvenience or aggravation, emotional distress or harm, commercial loss (including but not limited to lost profits or earnings), towing charges, bus fares, vehicle rental, service call charges, gasoline expenses, lodging expenses, damage to tow vehicle, and incidental charges such as telephone calls, facsimile transmissions, and mailing expenses. The above limitations and exclusions shall apply whether your claim is in contract, tort (including negligence and gross negligence), breach of warranty or condition, misrepresentation (whether negligent or otherwise), or otherwise at law or in equity, even if Tesla is advised of the possibility of such damages or such damages are reasonably foreseeable. Nothing in this Charging Equipment Limited Warranty shall exclude, or in any way limit, Teslaƒs liability for death or personal injury solely and directly caused by Teslaƒs negligence, or that of its employees, agents or sub-contractors (as applicable), fraud or fraudulent misrepresentation, or any other liability to the extent the same is proven in a court of competent jurisdiction in a final nonappealable judgment and may not be excluded or limited as a matter of local law. 30 Gen 3 Wall Connector Manual

Agreement to Arbitrate Please carefully read this provision, which applies to any dispute between you and Tesla, Inc. and its affiliates (together “Tesla”). If you have a concern or dispute, please send a written notice describing it and your desired resolution to [email protected]. If not resolved within 60 days, you agree that any dispute arising out of or relating to any aspect of the relationship between you and Tesla will not be decided by a judge or jury but instead by a single arbitrator in an arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules. This includes claims arising before this Charging Equipment Limited Warranty, such as claims related to statements about our products. Gen 3 Wall Connector Manual 31

WARRANTY INFORMATION Tesla will pay all AAA fees for any arbitration, which will be held in the city or county of your residence. To learn more about the Rules and how to begin an arbitration, you may call any AAA office or go to www.adr.org. The arbitrator may only resolve disputes between you and Tesla and may not consolidate claims without the consent of all parties. The arbitrator cannot hear class or representative claims or requests for relief on behalf of others purchasing or leasing Tesla products. In other words, you and Tesla may bring claims against the other only in your or its individual capacity and not as a plaintiff or class member in any class or representative action. If a court or arbitrator decides that any part of this agreement to arbitrate cannot be enforced as to a particular claim for relief or remedy (such as injunctive or declaratory relief), then that claim or remedy (and only that claim or remedy) shall be severed and must be brought in court and any other claims must be arbitrated. If you prefer, you may instead take an individual dispute to small claims court. You may opt out of arbitration within 30 days after signing this Charging Equipment Limited Warranty by sending a letter to: Tesla, Inc.; P.O. Box 15430; Fremont, CA 94539-7970, stating your name, product, and intent to opt out of the arbitration provision. If you do not opt out, this agreement to arbitrate overrides any different arbitration agreement between us, including any arbitration agreement in a lease or finance contract. 32 Gen 3 Wall Connector Manual
