Universal Wall Connector Manual 5 PRODUCT OVERVIEW Circuit Breaker Rating / Maximum Output Power Output For maximum power output, install a standard double pole 60 amp 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 50 40 30 20 15 48 40 32 24 16 12 11.5 9.6 7.6 5.7 3.8 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 27 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. For maximum power, check temperature rating of circuit breaker used:

For 60C rated circuit breaker, use minimum 4AWG, 90C THWN-2-rated copper wire for conductors. For 75C rated circuit breaker, use minimum 6AWG, 90C THWN-2-rated copper wire for conductors. NOTE: Increase conductor size if necessary. For sites with multiple Wall Connectors, the power sharing feature can enable the safe utilization of a single branch circuit. See single line examples in Breaker and Branch Circuit Setup on page 30. COPPER WIRE TERMINATIONS ONLY for landing in Wall Connector wirebox terminals. Conductors can be stranded or solid. Hardwire branch circuits to disconnects or circuit breakers. Do NOT install cord-and-plug type connections. For outdoor installations, use watertight fittings when securing feeder wires to the wirebox. Universal Wall Connector Manual 6 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. Install a ground (PE) wire sized according to local electrical code.

Universal Wall Connector Manual 8 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. Press and hold the button on the connector for 5 seconds. The Wall Connector will then be available to connect to WiFi for 15 minutes. 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. Universal Wall Connector Manual 9 PRODUCT OVERVIEW 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. A Wi-Fi connection is required for sites that utilize authentication, billing, and other property management features. Wall Connector only supports WPA2/3-secured, 2.4 GHz, 802.11 infrastructure mode networks. NOTE: Networks that are not password protected are not supported. The Wall Connector will not display non-password protected networks in the options list. Open networks without a password are not supported and will not be recognized by the Wall Connector. NOTE: WPA enterprise will be supported in a future firmware update. NOTE: Property management features will be enabled via future firmware updates. Universal Wall Connector Manual 10 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 ground 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 39 for a full list of fault codes. For ground assurance to operate on TN grids, one leg of the distribution transformer must be ground -

bonded (Neutral). Ground bond should only occur at one location in a site's electrical system. Wall Connector ground assurance may be adjusted in countries with TT or IT grid configurations and can be disabled in the commissioning procedure. The Ground Monitor Interrupter feature monitors the Wall Connector ground connection. Select the correct option based on the installation's earthing system and earth impedance. Depending on country, three options are available:

Enable: Ground connection will be monitored and a high detected. Ground resistance will disable the Wall Connector. This is the preferred setting to provide protection, and should be selected where ground connection is expected to be strong (as in the case on TN networks and most TT networks), and where required by regulation. Monitor: Ground connection will be monitored but a high detected ground resistance will not disable the Wall Connector. This should be selected if the ground monitoring check yields false positives and ground impedance cannot be improved (as is the case in some TT networks). Disabled: Ground connection will not be monitored. This should be selected where the ground connection is not made (as is the case for IT networks), or where the current induced by this check would be problematic (as is the case on some TT networks with sensitive residual-current devices). NOTE: Ground Monitoring is always enabled for installations in North America. Temporary problems such as ground faults or utility power surges are resolved automatically. Universal Wall Connector Manual 11 PRODUCT OVERVIEW 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 charge handle after power restoration will cause Wall Connector to resume charging immediately. NOTE: Wall Connectors in a power sharing group maintain their power shaing settings after a power loss event. 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 27.

Universal Wall Connector Manual 28 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. 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 NOTE: For instructions to commission Wall Connectors in a power sharing network, see Gen 3 Wall Connector Power Sharing. 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 Universal Wall Connector Manual 29 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 Single Branch Circuit Universal Wall Connector Manual 30 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 the Leader Wall Connector Wi-Fi, it is a good indication that the Follower 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 amperage:

Number of Wall Connectors: Max amperage output per Wall Connector when 100% utilized:

_____________________ ________________________ = ________________________ NOTE: Maximum number of Wall Connectors for power sharing is 6. 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 parking 3-5 (medium term) Workplace, hospitality 1-2 (short term) Shopping and dining 12+ amps 24+ amps 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. Setting Up Power Sharing Power sharing is a firmware feature that allows up to six Gen 3 Wall Connectors to limit their total grid current draw to a specified maximum current. This enables more connector installations and higher charging throughput by allowing individual Wall Connectors to be installed at their full current branch circuit capability, while setting a total allocated current so that the electrical service is not overloaded. Universal Wall Connector Manual 31 POWER SHARING Firmware Wall Connector firmware version 21.18.0 or higher is required for Power Sharing operation. Connecting a Wall Connector to local Wi-Fi will allow for automatic firmware updates.

(together Tesla). If you have a concern or dispute, please send a written notice describing it and your desired resolution to resolutions@tesla.com. Universal Wall Connector Manual 45 WARRANTY INFORMATION 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. 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.
