Note!
An additional mains isolation is required, if
l an 820X or 821X is connected to an INTERBUS master and
l a safe mains isolation (double basic insulation) is required
according to VDE 0160.
Use e.g. a bus terminal or an interface module for the INTERBUS
master with an additional mains isolation (see the corresponding
information of the manufacturer).
The incoming bus (IN) is isolated from the supply voltage and the
outgoing bus (OUT).
The supply voltage has the same potential as the outgoing data
bus (OUT).
l The bus system must be designed as a ring.
l Go-and-return lines are both in the same bus cable.
l The ring connects the INTERBUS master with all devices connected to the
bus.
