CHINA MAINLAND, HONG KONG 4
Service Wiring - Single Phase
WARNING: The Wall Connector is a
single-phase device. Do not connect all 3
phases of a 3-phase feed.
WARNING: Before 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 the local utility
company, or contact Tesla for assistance.
CAUTION: The line connection must
measure 220V RMS to neutral. earth
must also be connected to the Wall Connector.
For most branch circuits of 50A, use 16 mm
2
,
75°C hard copper wire. Ground wiring should
be at least 10 mm
2
. If your ground wiring does
not fit into the bus, use a wire nut or other
suitable connection method.
Run 32 mm metal pipe and flame retardant
conduit on the left side of a wall stud. The
conduit fits into the opening on either the back
or the left side of the Wall Connector as
described on page 8.
When connecting the line and neutral wires,
care must be taken that the service
transformer secondary connection is definitely
known, and the wires from the main circuit
breaker panel are correctly connected and
labeled. The illustrations provided show the
most commonly used wiring format in China.
NOTE: The line, neutral, and earth outputs
labeled on the illustrations correspond to the
inputs on the Wall Connector.
Ground (Earth) Connection
Always connect the earth line at the service
panel to earth. Ground fault protection is not
possible unless the earth line is connected to
earth.
If an earth connection is not available, 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 earth at that point.
WARNING: Follow local electrical codes
when installing the grounding stake.
IMPORTANT! Dip switch 4 must be set to
the 1 (left) position. See page 11.
