The plug-in power supply is ordered separately.
Procedure 5-4 Attaching the Power Supply to the I/O Module
Attach the power supply to the I/O module using the following procedure:
1) Put the plastic screw(s) in the hole(s) from under the board.
2) Screw the plastic spacer(s) onto the plastic screw(s).
3) Place the plug-in over the spacer(s).
4) Screw the top plastic screw into the spacer(s) to secure the plug-in.
The RTU will automatically recognize the 24V power supply.
Each plug-in power supply output is controlled by the CPU module. By default, the plug-in
power supply is ON and can supply up to 350mA. The power supply plug-in can be turned
ON/OFF via the user application program or Hardware Test utility.
Figure 5-7 provides a general view of an I/O module with one plug-in.
