Cerbo GX Manual

2.4. Connecting Victron products
2.4.1. Multis/Quattros/Inverters (VE.Bus products)
In order to keep this document short we are going to refer to all Multis, Quattros and Inverters as VE.Bus products.
The earliest version of the VE.Bus devices which can be connected to the Cerbo GX is 19xx111 or 20xx111, which were released
in 2007. VE.Bus firmware 26xxxxx and 27xxxxx are also supported …but 18xxxxx is not.
Note that it is not possible to use the Remote On/Off (header on the VE.Bus control PCB) in combination with a Cerbo GX. There
should be wire between the left and middle terminal, as it is when shipped from the factory. In case a wired switch that disables
the system is required, use the Safety Switch Assistant.
Single VE.Bus products
To connect a single VE.Bus product, connect it to one of the VE.Bus sockets on the back of the Cerbo GX. Both sockets are
identical, use either one. Use a standard RJ45 UTP cable, see our pricelist.
Parallel, split- and three-phase VE.Bus systems
To connect multiple VE.Bus products, configured as a parallel, split-phase or three phase VE.Bus system, connect either the first
or the last VE.Bus product in the chain to either one of the VE.Bus sockets on the back of the Cerbo GX. Use a standard RJ45
UTP cable, see our pricelist.
