Circuit Ratings

Use a single-phase circuit breaker rated for

50A single phase to obtain the highest power

output.

In certain installation locations, this level of

power isn’t readily available. Therefore, the

Wall Connector has an automatic load

management feature that allows the output

current to be adjusted to any circuit breaker

ranging from 15A to 50A (refer to Set the

Operating Current on page 18).

Note: Actual amperage draw will depend on

the on-board charger of the vehicle. Contact

Tesla if you have questions about the on-

board charger of a speciﬁc vehicle.

Self-Monit

oring and Recovery

The Wall Connector has a ground monitoring

circuit that continuously checks for the

presence of a safe ground connection and

automatically recovers from faults. Manual

testing and resetting is not required.

Temporary problems such as ground faults or

utility power surges are overcome

automatically. If a residual current fault occurs

that interrupts charging, the Wall Connector

automatically tries to clear the fault and re-

attempt charging.

If the problem is immediately sensed a second

time, the Wall Connector waits 15 minutes

before trying to charge. This process repeats 4

times and if all attempts are unsuccessful,

power is removed and no further attempts are

made. In this case, you will see a red error light

on the front panel (refer to Troubleshooting

on page 21). It is recommended that when

you see a red error light, you power o the

W

all Connector by switching o the upstream

cir

cuit breaker, and then power it back on

again.

The Wall Connector can alternatively be reset

when a red error light is encountered using

the RESET button (refer to Reset on page

24).

Power Outages

If a po

wer outage occurs, the Wall Connector

automatically resumes charging when power

is restored. If the charging cable is plugged

into the vehicle when power is restored, the

lights blink and the unit does not energize the

charging cable for approximately 15 seconds

to three minutes. This prevents the utility grid

from experiencing a large surge when power is

restored and allows vehicles to begin drawing

current at random times, rather than all at

once.

Load Sharing

Up to 4 Wall Connectors can be wired to a

single circuit, and with built-in automatic load

management, vehicle owners can easily

charge multiple vehicles at home (refer to

Appendix B: Optional Connection for Load

Sharing on page 27).

Features

6

Minimum Requirements

Installation of the Wall Connector requires that

you:

• Calculate the existing electrical load to

determine the maximum operating

current.

• Calculate the distance to ensure minimal

voltage drop.

• Obtain any necessary permits from the

local authority that has jurisdiction and

conﬁrm that the follow-up inspection has

been scheduled by an electrician after the

installation is complete.

• Use only copper conductors.

• Use conductors that are sized in

accordance with local wiring regulations.

The selected cable must be able to sustain

periods of constant load of up to the

maximum amperage selected by the

electrician.

• Use a circuit breaker.

Note: Consult with an electrician to ensure

that the installation meets local regulations.

120V Above Ground

Warning: T

he Wall Connector is a single-

phase device. Do not connect all three

phases of a three-phase feed.

Warning: Bef

ore installing the Wall

Connector, identify the type of utility

service connection available on site. If you

are unsure about the type of connection

available at the service panel, consult an

electrician, or contact Tesla for assistance.

Caution: T

he two phases used must each

measure 120V to neutral. Earth ground

must be connected to neutral at only one

point, usually at the breaker panel.

Caution: If a 240V thr

ee-phase feed is

from a Delta-connected secondary, the

leg used must have a center tap. This

center tap must be grounded. Only the

two phases on either side of the center-

tapped leg can be used.

Only three wires are connected, but care must

be tak

en that the service transformer

secondary connection is deﬁnitely known, and

that the three wires from the main circuit

breaker panel are correctly connected and

labeled.

Note: The L1, L2, and ground outputs labeled

on the illustrations correspond to the inputs

on the Wall Connector.

Ground Connection

Always connect the Neutral at the service to

Earth Ground. Ground fault protection is not

possible unless the Neutral (center tap on the

service transformer) is connected to an Earth

Ground. If ground is not provided by the

electrical service, you must install a grounding

stake nearby. the grounding stake must be

connected to the ground bar in the main

breaker panel, and Neutral connected to

Ground at that point.

208V 3-Phase Wye-Connected

With a Wye-connected secondary, any two of

the legs can be used to provide 208V to the

Wall Connector. For example, L1 and L2, or L1

and L3, or L2 and L3. The two used phases

must each measure 120V to neutral.

Note: A current-carrying neutral is not

required.

Caution: The unused leg (L3 in the

illustration) must remain open. Do not

connect to a neutral bar, or to earth

ground.

Caution: The center point of the three

phases (normally used as neutral) must

be grounded to earth at only one point.

This is usually at the breaker panel.

240V Three-Phase Delta-

Connected

With the delta connection, one leg must be

center tapped, and only the two phases on

either side of the center tap can be used. The

two used phases must each measure 120V to

neutral.

Consult the transformer manufacturer’s

literature to verify that the single leg can

supply the required power.

Note: The Wall Connector’s contactor closes

only if it detects the presence of an earth

ground wire connected to a neutral point on

the transformer secondary.

respect to neutral, and is sometimes

referred to as a “stinger.” Do not use this

third line.

Caution: Do not use a three-phase delta-

connected transformer secondary

without a center tap on one leg. No

neutral point is available for the required

earth ground connection.

Determine the Circuit Breaker

Requirements

To determine the type of upstream circuit

breaker you need, examine the distribution

panel or circuit breaker box to identify the

amperage available at the installation site.

Planning Your Installation

The Wall Connector has an internal rotary

switch that allows you to adjust its operating

current (refer to Set the Operating Current on

page 18). The circuit breaker should be

rated for the continuous current of 40A.

Choose the Best Location for the

Wall Connector

Determine the parking location of the vehicle

to ensure that the charge cable reaches the

charge port. The Wall Connector should be

located:

• In an enclosed garage, typically on the

vehicle's charge port side.

• In a well-ventilated area. Avoid installation

in an enclosed box, or adjacent to hot

appliances.

• 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 for

outdoor use, but it is not designed for

complete immersion in liquid. Protection from

rain is recommended but not required.

Installation Considerations

Three methods are available to install the Wall

Connector. The location of the conduit and

type of wiring determine which installation

method to follow:

• If the conduit runs along the ﬂoor or low

on the wall, use the bottom entry

conﬁguration.

• If the conduit comes from inside the wall,

use the r

ear entry conﬁguration.

• If the conduit comes from the ceiling, or if

the service wiring is thicker than 6 AWG,

use the top entry conﬁguration. The top

entry br

acket has an optional rear-facing

knockout that allows thicker service wiring

to enter from the top or rear.

Note: Throughout the manual, “conduit” is

used as the standard term for the protective

tubing that houses the service wiring. In

regions where conduit is not used (Europe for

example), a cable comprised of service wiring

enclosed in a protective jacket may be

substituted for conduit if allowed 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.

• Use a UL approved conduit connector to

ensure proper seal.

• When installing wire thicker than 6 AWG,

use the top entry installation.

Install the Low Proﬁle Bracket for

Rear or Bottom Entry Wiring

Use the low proﬁle bracket, shown below, to

wire the Wall Connector from the rear or

bottom.

1. Use the low proﬁle bracket as a guide to

mark the location on the wall for the

mounting screws.

• Use a level to ensure that the marks

are perfectly vertical.

• Space the holes 4.5" (114 mm) apart.

• For U.S.A. installations, position the

br

acket so that the Wall Connector is

located at a maximum of 60" (150 cm)

from ﬂoor level. The minimum height

is 18" (45 cm) if mounting indoors,

and 48" (122 cm) if mounting

out

doors.

• If using the rear entry conduit, use at

least one set of the edge mounting

holes so that the conduit does not

interfere with the wall stud.

• If using the bottom entry conduit, use

the two center mounting holes.

Note: Ensure that the minimum and

maximum height of the bracket is carefully

selected. It should be installed out of the

way of any reasonably foreseeable

impacts.

2. Attach the bracket using fasteners that

are appropriate for the type of wall

material, drilling pilot holes if necessary.

Use the supplied screws only if mounting

the bracket directly to a wooden stud. If

mounting to another type of wall (hollow,

masonry, etc.), use fasteners that are long

enough to securely anchor the Wall

Connector and can hold at least 80 lb (36

kg).

Step-by-Step Installation Instructions

Step-by-Step Installation Instructions 13

Install the Top Entry Bracket for

Rear or Top Entry Wiring

The top entry bracket enables you to route the

service wiring into the Wall Connector

enclosure from the top of the enclosure, as

shown below.

1. Use the cardboard template and a level as

a guide to mark the location on the wall

for the mounting screws.

Step-by-Step Installation Instructions 15

Connect the Wiring

Note: Consult with your local electrician or

refer to your local code for proper wire sizing

appropriate for the currents in your Wall

Connector.

Note: It is the installer's responsibility to

identify whether additional grounding is

required to ensure that local regulations are

met. Grounding must be installed at the power

source and not at the cable entry to the Wall

Connector.

Warning: Do not connect service wiring

until you have read and fully understand

the concepts described in this section. If

you are uncertain about the type of

power available at the service panel,

consult an electrician, or contact Tesla for

assistance.
