Circuit Ratings

Use a single-phase circuit breaker rated for100A single phase to obtain the fastestcharging.

In certain installation locations, this level ofpower isn’t readily available. Therefore, youcan adjust the circuit breaker rating on theWall Connector from 15A to 100A (refer to Setthe Operating Current on page 21).

Note: Actual amperage draw will depend onthe on-board charger of the vehicle. ContactTesla if you have questions about the on-board charger of a specific vehicle.

Self-Monitoring and Recovery

The Wall Connector has a ground monitoringcircuit that continuously checks for thepresence of a safe ground connection andautomatically recovers from faults. Manualtesting and resetting is not required.

Temporary problems such as ground faults orutility power surges are overcomeautomatically. If a residual current fault occursthat interrupts charging, the Wall Connectorautomatically tries to clear the fault and re-attempt charging.

If the problem is immediately sensed a secondtime, the Wall Connector waits 15 minutesbefore trying to charge. This process repeats 4times and if all attempts are unsuccessful,power is removed and no further attempts aremade. In this case, you will see a red error lighton the front panel (refer to Troubleshootingon page 24). It is recommended that whenyou see a red error light, you power off theWall Connector by switching off the upstreamcircuit breaker, and then power it back onagain.

The Wall Connector can alternatively be resetwhen a red error light is encountered usingthe RESET button (refer to Reset on page27).

Power Outages

If a power outage occurs, the Wall Connectorautomatically resumes charging when poweris restored. If the charging cable is pluggedinto the vehicle when power is restored, thelights blink and the unit does not energize thecharging cable for approximately 15 secondsto three minutes. This prevents the utility gridfrom experiencing a large surge when power isrestored and allows vehicles to begin drawingcurrent at random times, rather than all atonce.

Load Sharing

The Wall Connector provides the capability towire 4 Wall Connectors to a single circuit withautomatic load management, giving vehicleowners reassurance that they can chargemultiple vehicles at home (refer to AppendixB: Optional Connection for Load Sharing onpage 30).

Minimum Requirements

Installation of the Wall Connector requires thatyou:

• Calculate the existing electrical load todetermine the maximum operatingcurrent.

• Calculate the distance to ensure minimalvoltage drop.

• Obtain any necessary permits from thelocal authority that has jurisdiction andconfirm that the follow-up inspection hasbeen scheduled by an electrician after theinstallation is complete.

• Use only copper conductors.• Use conductors that are sized in

accordance with local wiring regulations.The selected cable must be able to sustainperiods of constant load of up to themaximum amperage selected by theelectrician.

• Use protective devices. The circuitprotection device chosen mustincorporate overcurrent protection inrelation to the electrical load selected.

Note: Consult with an electrician to ensurethat the installation meets local regulations.

Service Wiring

Warning: The Wall Connector is a single-phase device. Do not connect all threephases of a three-phase feed.

Warning: Before installing the WallConnector, identify the type of utilityservice connection available on site.

Caution: If a 240V three-phase feed isfrom a Delta-connected secondary, theleg used must have a center tap. Thiscenter tap must be grounded. Only thetwo phases on either side of thecentertapped leg can be used.

Only three wires are connected, but care mustbe taken that the service transformersecondary connection is definitely known, andthat the three wires from the main circuitbreaker panel are correctly connected andlabeled.

Caution: The two phases used must eachmeasure 120V to neutral. Earth groundmust be connected to neutral at only onepoint, usually at the breaker panel.

Single-Phase With Neutral

For single-phase use of a Wye-connectedsecondary, only a single-phase (L1) and neutralshould be connected. The phase to neutralvoltage measurement are shown in theillustration below.

Warning: The Wall Connector in thisconfiguration operates only from a single-phase (L1). Do not connect the remainingphases (L2 and L3).

Warning: Before installing the WallConnector, identify the type of utilityservice connection available on site. If youare unsure about the type of connectionavailable at the service panel, consult anelectrician, or contact Tesla for assistance.

Note: Consult with your local electrician orrefer to your local code for proper wire sizingappropriate for the currents in your WallConnector.

Single-Phase Without Neutral

Determine the Circuit BreakerRequirements

To determine the type of upstream circuitbreaker you need, examine the distributionpanel or circuit breaker box to identify theamperage available at the installation site.



The Wall Connector has an internal rotaryswitch that allows you to adjust its operatingcurrent (refer to Set the Operating Current onpage 21). The circuit breaker should be ratedfor the continuous current of: 12, 16, 20, 24, 28,32, 36, 40, 48, 56, 64, 72, or 80A.

Note: Refer to the circuit breaker currentratings specified on IEC 60898 when installingthe Wall Connector. If in doubt, check withyour local building electrical inspector.

Choose the Best Location for theWall Connector

Determine the parking location of the vehicleto ensure that the charge cable reaches thecharge port. The Wall Connector should belocated:

• In an enclosed garage, typically on thevehicle's charge port side.

• In a well-ventilated area. Avoid installationin an enclosed box, or adjacent to hotappliances.

• 4 ft (1.2 m) above the floor.• 8 in (190 mm) from any obstructions to

allow for cable looping.

Note: The Wall Connector is approved foroutdoor use, but it is not designed forcomplete immersion in liquid. Protection fromrain is recommended but not required.


10

Installation Considerations

Three methods are available to install the Wall Connector. The location of the conduit determineswhich installation method to follow. If the conduit runs along the floor or low on the wall, use thebottom entry configuration. If the conduit comes from inside the wall, use the rear entryconfiguration. If the available conduit comes from the ceiling, use the top entry installation.

Note: Throughout the manual, “conduit” is used as the standard term for the protective tubingthat houses the service wiring. In regions where conduit is not used (Europe for example), a cablecomprised of service wiring enclosed in a protective jacket may be substituted for conduit ifallowed by local regulations.

Here are some additional guidelines:

• Conduit openings are sized for 1" (25 mm) conduit.• Conduit needs to meet all local regulations.• Use an appropriate circuit breaker.• To keep the housing weatherproof, use cable glands.• Use a UL approved conduit connector to ensure proper seal.

Reset

If a fault causes a RED error light to illuminate or flash and the fault condition is corrected, you useRESET the Wall Connector to resume normal operation. There are two ways to REST the WallConnector:

• Press the RESET button for two to three seconds until the top lights changes from RED toGREEN. This clears the fault message but does not reboot the Wall Connector.

• In a rare situation, you might need to force the Wall Connector to reboot without recycling theinput power. Hold the RESET button for five seconds. When the top light changes from REDto GREEN, release the RESET button. The top light should continue to illuminate GREEN. If thelight returns to flashing RED, the fault state has not been corrected.

1. Turn OFF power.

Warning: RISK OF ELECTRIC SHOCK!Before continuing, use a voltmeter toensure the power is off by confirmingthat NO VOLTAGE is present at theservice wiring or terminals.

2. Use a non-conductive object to adjust theDIP switches to the appropriate gridsetting and circuit breaker sharing setting(refer to Set the Operating Current onpage 21).

3. Use a small flathead screwdriver to set therotary switch to position "0" to put theWall Connector into Test Mode.

Warning: Power MUST remain OFFbefore setting or changing the DIP orrotary switches. Changing theseswitches with the power ON will notbe recognized by the system and isdangerous due to the risk of electricshock.


5. Use a T20 security pin Torx driver tolightly secure the sealing cover byinstalling only the top screw.

6. Turn ON the circuit breaker.7. Watch for any Red LEDs to be ON after a

sequence of LED display; if so, there is afault in the installation.

8. Listen for the click of a contactor or relayclosing and opening.

9. Watch for Green streaming LEDs (for 5seconds).

LEDs will revert to top Green LED ON andRed LEDs flashing (3 times).

Note: To review the pattern of blinkinglights, press and hold the Reset button for5 seconds.

10. Turn OFF the circuit breaker.11. Remove the sealing cover screw, sealing

cover. Disconnect the ribbon cable.

Caution: Do not allow the sealingcover to hang from the ribbon cable.Doing so can damage the ribboncable or its connectors.

12. Reposition the rotary switch to theappropriate setting (refer to Set theOperating Current on page 21).


14. Replace all the screws and reinstall theouter cover (refer to Secure the Cover andPower Up on page 22).

Appendix A: Testing for Proper Operation

Appendix A: Testing for Proper Operation 29

The Wall Connector includes an automaticload management feature whereby WallConnector to Wall Connector communicationallows you to split the maximum available loadover a maximum of 4 Wall Connectors. Thewire used for this local network must:

• Share the main power cable conduit or behoused in a separate conduit. In otherwords, the high voltage wires must bebranched to a junction box from eachindividual unit.

• Be at least 18 AWG, 2 conductor, shielded,twisted-pair wire.

Warning: When load sharing, high voltage(L1, L2, Neutral, Earth) cabling must bespliced in a separate NEMA ratedenclosure.

Note: Take additional precautions intoconsideration to prevent water ingress at theWall Connectors when installing themoutdoors.

Note: Consult with an electrician to ensurethat the installation meets local regulations.

Daisy Chaining Multiple WallConnectors

Each Wall Connector has one terminal blockdedicated for the communication wiring asshown below. The left hand side of theterminal block is the input terminal and theright hand side the output terminal.

1. Form a daisy-chained network by connecting the cables from OUT to IN and always from positive to positive and negative to negative between each of the participating Wall Connectors (refer to Example of the Communication Wiring on page 31).

• The signal wires between each Wall Connector should run in signal conduit. Use a 1/2" (13 mm) UL approved conduit hub to seal the signal conduit opening.

• If the signal wire is routed in the power conduit with the power wires, the insulation rating of the signal wire should be equal to or greater than that of the power wires.

• The maximum distance between Wall Connectors is 49 ft (15 m).

2. Set one Wall Connector as the leader by setting the Rotary Switch Position from 1 through D, depending on the maximum available output current. Set up to 3 Wall Connectors as followers by setting the Rotary Switch Positions to F. In the load sharing network, only one unit can be designated

Appendix B: Optional Connection for Load Sharing

30

as the leader (refer to Set the Operating Current on page 21).

3. Confirm that the load sharing network isproperly installed by observing the LEDindicators in the Wall Connector. Whenstarting up the circuit breaker for the firsttime, green lights turning ON for 5seconds indicate a proper installation. Thefinal display is:

Other Load Sharing Behaviors

• Available current is redistributed equally among all connected vehicles whenever a new vehicle is plugged or unplugged from the network.

• During steady-state operation, the load sharing network toggles available current to each vehicle in 2A increments, every minute, to asses vehicle need. When a battery approaches full charge, the power consumption will taper until charging is complete. If the leader unit detects that a vehicle is no longer using all of its available current, it will reduce the current allocated to that vehicle

• A follower Wall Connector will not charge if communication is lost with the leader Wall Connector.

• In rare cases, firmware updates on a leader Wall Connector will interrupt charging on the follower Wall Connector(s). This is normal behavior, and charging should resume once the firmware update is complete (15 minutes).
