You can use this procedure to connect the MD 748i-11-42/L5-2222 to a power supply.
Note: Power should be disconnected from the power supply before connecting it to the MD 748i-11-42/L5- 2222.
Otherwise, your screwdriver blade can inadvertently short your power supply terminal connections to the
grounded enclosure.
1. Securely attach the power cable between the male power connector (PWR In) and the power
supply.
2. Either attach a power cable between the female power connector and another device to which you
want to provide power or securely attach a connector cap to prevent dust or liquids from getting into
the connector.
3. Apply the power and verify that the following LEDs are lit indicating that you are ready to attach your
IO-Link or digital I/O devices.
 PWR - green lit LED indicates the MD 748i-11-42/L5-2222 is receiving power.
 MOD - this LED is not lit, which indicates there are no errors
 NET - this LED is off unless a PLC is connected. If a PLC is connected, the LED is lit and green.
 LINK should be lit (green) to indicate a valid network connection.
 ACT blinks if there is network traffic between the IO-Link Master and the network.
 EIP 1/2 should be lit (green) indicating that the link is up if both connectors are connected.
 Port LEDs should display in this manner if there is no device attached:
 IO-Link port
device.
 DI should be off to indicate that there is no device attached to the port.
If the LEDs indicate that you are ready to go to the next installation step:
 Program the IP address using the web interface. Refer to chapter 3 for configuring the network
information.
 If using the rotary switches to set the IP address, then you are ready to attach devices using
chapter 6.
If the LEDs do not meet the above conditions, you can refer to the IO-Link Master
