Connecting the power supplies

Supply the Inline controller using external 24 V DC voltage sources. The permissible voltage
ranges from 19.2 V DC to 30 V DC (ripple included).
Only use power supplies that are suitable for operation with capacitive loads (increased
switch-on current) (see Section "Sizing of the power supply" on page 37).
1. Connect the power supplies to the connector for power supply as shown in Figure 2-23.
2. Insert the connector in the Inline controller.
3. Switch on the power supplies.
4. The UL, UM, and US LEDs light up and, after around 10 seconds, the FR and RDY
LEDs start flashing.
The Inline controller is now fully initialized.
If the LEDs do not light up or start flashing, there is a serious fault on the Inline controller. In
this case, please contact Phoenix Contact.
