|  | IOLM DR-8-PNIO Connect the Power
The IOLM DR-8-PNIO provides two redundant power inputs with screw terminals on the top and bottom of the IOLM DR-8-PNIO.
![[Note]](images/note.gif) | | Note |
|---|
Use either power terminals (top or bottom) but do not use both to supply power to the IOLM DR-8-PNIO.

The following provides power information for the IOLM DR-8-PNIO.
The following table provides signal information.
Power Supply Current and VoltageMaximum EMC protection is provided by a low impedance connection between functional earth,
the ground when connected to a ground DIN rail, and protective earth. The following table contains power-related information about the power supply.
| | Note |
|---|
The total supply of current for all connected IO-Link devices.
IOLM DR-8-PNIO requires a UL listed power supply with an output rating of 24VDC. |
|
You can use this procedure to connect the IOLM DR-8-PNIO to a power supply.
| | Note |
|---|
Power should be disconnected from the power supply before connecting it to the IOLM DR-8-PNIO.
Otherwise, your screw driver blade can inadvertently short your terminal connections to the grounded enclosure. |
|
Insert positive and negative wires (12-24AWG) into the V+ and V- contacts.
You can refer to the port placement. Tighten the wire-clamp screws to prevent the wires from coming loose. Apply the power and verify that the following LEDs are lit indicating that you are ready to begin configuration.
PWR - The LED is lit indicating that the IO-Link Master is
receiving power. MS - The MS LED is off, which means that the IOLM is operating as expected.
| | Note |
|---|
If the IOLM DR-8-PNIO has U-Boot bootloader v1.25 or higher, the MS LED is lit during the power-on cycle. |
|
NS - if the NS LED is off;
that means that there is no PLC connected. If the NS LED is lit and green, that
means that a PLC is connected.
| | Note |
|---|
If the IOLM DR-8-PNIO has U-Boot bootloader v1.25 or higher, the NS LED is lit during the power-on cycle. |
|
The Link LEDs should be steady green indicating that the link is up.
The ACT LED flashes to indicate network activity.
