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.
EtherCAT
®
communication interface
This interface can be found on the interface module in the form of two 8-pin RJ45 sockets on
the bottom of the housing.
Insert the EtherCAT
®
connectors into one of the RJ45 socket(s) with the inscription "In" (cable
from master) or "Out" (further cable to the next EtherCAT
®
slave).
Preparing for operation on the 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-."
