Optional Circuit Ratings

Use a single-phase circuit breaker rated for100A per phase to obtain the fastest charging.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 20).

Note: Tesla vehicles must be configured withoptional onboard charging equipment toaccept higher amperages. Contact Tesla if youhave questions about the onboard chargingcapabilities of your 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 22). 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 page25).

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,giving vehicle owners reassurance that theycan charge multiple vehicles at home (refer to Appendix B: Optional Connection for LoadSharing on page 28).

Features

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 themaxium amperage selected by theelectrician.

• Use protective devices. The circuitprotection device chosen mustincorporate a suitable residual-currentdevice (RCD) and overcurrent protectionin relation to the electrical load selected.

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

Service Wiring

120V Above Ground

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. If youare unsure about the type of connectionavailable at the service panel, consult anelectrician, or contact Tesla for assistance.

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

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 the center-tapped 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.

Note: The L1, L2, and ground outputs labeledon the illustrations correspond to the inputson the Wall Connector.

Ground Connection

Always connect the Neutral at the service toEarth Ground. Ground fault protection is notpossible unless the Neutral (center tap on theservice transformer) is connected to an EarthGround. If ground is not provided by theelectrical service, you must install a groundingstake nearby. the grounding stake must beconnected to the ground bar in the mainbreaker panel, and Neutral connected toGround at that point.

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.


8

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

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.



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 20).

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 20).


14. Replace all the screws and reinstall theouter cover (refer to Secure the Cover andPower Up on page 21).

Appendix A: Testing for Proper Operation

Appendix A: Testing for Proper Operation 27

The Wall Connector includes a featurewhereby Wall Connector to Wall Connectorcommunication allows you to split themaximum available load over a maximum of 4Wall Connectors. The wire used for this localnetwork must share the main power cableconduit or be housed in a separate conduit. Inother words, the high voltage wires must bebranched to a junction box from eachindividual unit.

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

Warning: A 600V rated, minimum 18 AWG(1 mm), 2 conductor shielded twisted-pairwire must be used when creating a localnetwork for load sharing.

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 byconnecting the cables from OUT to IN andalways from positive to positive andnegative to negative between each of theparticipating Wall Connectors (refer to Example of the Communication Wiring onpage 29).

• The signal wires between each WallConnector should run in signalconduit. Use a 1/2" (13 mm) ULapproved conduit hub to seal thesignal conduit opening.

• If the signal wire is routed in thepower conduit with the power wires,the insulation rating of the signal wireshould be equal to or greater thanthat of the power wires.

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

• Use twisted pair cable for the signalwire.

2. Set one Wall Connector as the master bysetting the Rotary Switch Position from 1through D, depending on the maximumavailable output current. Set up to 3 WallConnectors as slaves by setting the Rotary
