The Wall Connector includes a feature
whereby Wall Connector to Wall Connector
communication allows you to split the
maximum available load over a maximum of 4
Wall Connectors. The wire used for this local
network must share the main power cable
conduit or be housed in a separate conduit.
You can connect the Wall Connectors in series
in a daisy chain configuration.
Note: Take additional precautions into
consideration to prevent water ingress at the
Wall Connectors when installing them
outdoors.
Note: Consult with an electrician to ensure
that the installation meets local regulations.
Daisy Chaining Multiple Wall
Connectors
Each Wall Connector has one terminal block
dedicated for the communication wiring as
shown below. The left hand side of the
terminal block is the input terminal and the
right 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 30).
•
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).
•
Use twisted pair cable for the signal
wire.
Note: Tesla recommends that you use a
shielded cable to limit potential
interference.
2. Set one Wall Connector as the master by
setting the Rotary Switch Position from 1
to 8 depending on the maximum available
output current. Set up to 3 Wall
Connectors as slaves by setting the Rotary
Switch Positions to F. In the load sharing
network, only one unit can be designated
as the master (refer to Set the Operating
Current on page 21).
3. Confirm that the load sharing network is
properly installed by observing the LED
indicators in the Wall Connector. When
starting up the circuit breaker for the first
time, Green lights turning ON for 5
seconds indicate a proper installation as
follows:
