Design Of A Local Charging Network (Master/Slave) - ABB EVLUNIC PRO M Configuration Manual

The commissioning of the GSM module is described in the "Installation Manual". The technical data of
the GSM interface and the SIM card can also be found in the "Installation Manual".

2.2. Design of a local charging network (master/slave)

A local charging network includes one EVLunic Pro M as master and up to 15 EVLunic Pro S as slaves.
Depending on the number of slave charging stations, the design of a local charging network is
implemented differently:
• 1 slave charging station: Direct connection
The slave charging station is connected directly to the master charging station.
• Multiple slave charging stations: Connection via router or switch
The slave charging stations are connected to the master charging station via a router or switch.
To enable communication between master and slave charging stations, the charging stations must be
configured in the web interface, see 3 Configuration.
2.2.1. Displays and signals
The display on the front of the charging station provides information about which communication
connection is established.
