Installation
Connecting the Power Supply
Connect the operating voltage (10 VDC...33 VDC) to Terminals 1 and 2 of the 4-pin plug X2 on
the interface module. In addition, note the label on the module.
The "Power" LED lights up green.
Equipotential Bonding Connection
The connection to equipotential bonding occurs automatically when attaching to the DIN
mounting rail.
PROFIBUS DP Communication Interface
This interface can be found on the front of the housing in the form of a 9-pin D-SUB socket.
1. Connect the PROFIBUS connector to the D-SUB socket labeled "PROFIBUS."
2. Tighten the lock screws on the connector using a screwdriver.
3. If the assembly is at the beginning or at the end of the PROFIBUS cable, you must connect
the terminator that is integrated in the interface module. To do this, slide the sliding switch to
the "on" position or to the upper end position.
4. If the module is not at the beginning or at the end, you must slide the sliding switch to the
"off" position or to the lower end position.
Preparing for Operation on RS-485 Interface
For operation on an RS-485 interface, the terminals on connector X1 must be connected as
follows:
1. Connect Terminal 4 "Rx 422+" to terminal 6 "Tx 422+."
2. Connect Terminal 5 "Rx 422-" to terminal 7 "Tx 422-."
