Fig. 7-6 IGB network
PC or the internet are connected to a free outer socket. The IGB network is set
up automatically when you turn on at least one inverter. The following conditions
apply when integrating additional inverters into the network:
• You have connected these inverters to the IGB network.
• The inverters in the network must be receiving a 24-V power supply.
To start the integration, the 24-V power supply of the inverter in the network must
be turned on. When the 24-V power supply is turned on, the IGB network is
restructured and up to 32 connected inverters will be integrated.
