a. Connect the power wires and the PE/G wire of the power cable to the input terminals on the
terminal block.
Note:
When multiple charging stations are connected to one power supply cabinet, consider
using phase rotation (see
Phase rotation on page 21 ).
b. Pull on the wires to make sure they are correctly connected. The indicators on the terminal
block must be in the locked position.
5. Secure the power supply cables with one or more cable ties.
4.2.3. Connect Hub-Satellite network cables
See the corresponding illustrations in manual B.
In a Hub-Satellite system, the hub contains the communication module and communicates with the
satellite stations using a data cable. The network cables are attached in series between the
communication port of each satellite then to the communication port in the hub. The communication
port is the black 2-pin connector on the right side of the controller.
• Use a RS485 connector, 2-pin, black, for each RS485 connection.
• Use SFTP Category 6 network cable suited to the RS485 protocol for the data connection.
• Use the green/green-white twisted pair of wires for the RS485 connections.
• One BusinessLine hub can be connected to a maximum of 19 BusinessLine satellites.
• In a double BusinessLine station, the RS485 connection between the hub and satellite (or satellite
and satellite) is already in place. Make sure to connect the incoming RS485 cable on one side of
the station (for a Satellite) and the outgoing RS485 cable on the other side of the station to ensure
a proper serial network.
• Always terminate the Hub-Satellite network with a 120 Ω terminal resistor (see Delivered
components on page 13 ) on the black RS485 connector of the last station in the series.
• For correct operation of a smart grid, a Hub-Satellite configuration must be connected from a
single power cabinet. If a group of charging stations is powered from a different power cabinet
then that group stations must be a separate Hub-Satellite configuration.
• This method of installation cannot be used in a Star-shaped or T-shaped network because
reflections can occur in the cable.
• In a Hub-Satellite installation, if one or more LED rings constantly flash red then there is a crossed
connection in one of the satellite RS485 connections.
Connect the Hub-Satellite network cables in accordance with the diagram.
Note:
RS485 data communication configurations in a Star-shaped or T-shaped network will not function
correctly because signal reflections can occur in the network. Refer to the schematics for
examples of Star-shaped and T-Shaped networks.
