Check Status Indicators
Before you apply power, you must install and mount a CompactLogix controller
and Compact I/O™ power supply on the DIN rail.
Follow these steps to apply power.
1. Flip the switch to the ON position.
2. Check the power supply (1) and module (2) status indicators.
3. Check the alphanumeric display to determine that the power supply and
module are operating properly.
Remove the Module
Follow these steps to remove the communication module.
When you turn off the CompactLogix power supply, make sure that you wait for
all status indicators on the power supply and controller to turn off before
disconnecting any part from the system.
If you disconnect the CompactLogix system while the controller is still writing
its program to memory, the program write is not completed and your program
is lost.
