UMG 512-PRO
8.3 Profibus interface
This RS-485 interface, designed as a 9-pin DSub
socket, supports the Profibus DP V0 Slave proto-
col.
For easy connection of incoming and outgoing
bus lines, connect them to the device via a Profib-
us connector.
For connection, we recommend a 9-pin Pro-
fibus connector, e.g. from Phoenix of the type
"SUBCON-Plus-ProfiB/AX/SC" with part number
2744380.
(Janitza Part. no.: 13.10.539)

INFORMATION
When using the device in a Profibus system, set
the device address via the configuration menu
as described in „11.2.2 Fieldbus“ on page
55!
8.3.1 Connecting the bus lines
1.Connect the incoming bus line to terminals 1A
and 1B of the Profibus connector.
2.Connect the continuing bus line for the next
device in the line to terminals 2A and 2B.
3.If no further device follows in the line, terminate
the bus line with resistors by setting the switch
on the Profibus connector to ON.

WARNING
Risk of injury due to electrical voltage!
The Profibus, RS-485, temperature measurement
input and residual current measurement input are
not galvanically isolated from each other.
It is therefore essential to note that dangerous
voltages at these inputs can have an effect on
the respective other connections.
