Connecting the Power
2.4. Connecting the Power
The IO-Link Master provides dual M12 (A-coded) power connectors.
Maximum EMC protection is provided by a low impedance connection between functional earth, the
grounding tabs, and protective earth. The following table contains power-related information about the power
supply.
Note: IO-Link Master requires a UL listed power supply with an output rating of 24VDC.
You can use this procedure to connect the IO-Link Master to a power supply.
1. Securely attach the power cable between the male power connector 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. Connector caps were shipped with the IO-Link Master.
3. Apply the power and verify that the following LEDs are lit indicating that you are ready to begin
configuration.
• PWR
• MS, first the flashing green and red LEDs displays that it is in self-test mode. After the self-test,
depending on whether you set the IP address with the rotary switch one of the following occurs:
- The green LED is flashing to indicate that it is in standby mode.
- The green LED is lit to indicate that it is operational.
• NET, first it flashes green and red indicating that it is in self-test mode. After the self-test, depending
on whether you set the IP address with the rotary switch one of the following occurs:
- Off indicates there is no IP address
