Connecting the IOLM (Power and Network)
For detailed procedures, refer to the appropriate guide for your model:
•
IO-Link Master 4-EIP User Guide
•
IO-Link DR-8-EIP User
The IO-Link Master is referred to simply as the IOLM in this document unless there is specific information
about a specific model.
Use the appropriate discussion for you IOLM model.
•
DR-8-EIP (IP20 DIN rail)
•
4-EIP (IP67 with rotary switches)
DR-8-EIP (IP20 DIN Rail)
The following procedures discuss connecting the IOLM DR-8-EIP power and network.
Connecting to the Network
The IOLM DR-8-EIP provides two Fast Ethernet (10/100BASE-TX) RJ45 connections.
1. Securely connect one end of the RJ45 Ethernet cable to either Ethernet port.
2. Connect the other end to the network.
3. Optionally, you can use the other Ethernet port to daisy-chain to another Ethernet device.
Connecting the Power
Use either power terminal (top or bottom) but do not use both to supply power to the DR-8-EIP.

You can use this procedure to connect the DR-8-EIP to a power supply.
Note:
Disconnect the power from the power supply before connecting it to the DR-8-EIP. Otherwise,
your screw driver blade can inadvertently short your terminal connections to the grounded
enclosure.
1. Insert positive and negative wires (12-24AWG) into the V+ and V- contacts.
2. Tighten the wire-clamp screws to prevent the wires from coming loose.
