DANGER
Risk of electric shock!
Risk of serious injury or death due to electric shock. Some parts of the main
board may still carry 230 V voltage even with the device physically isolated
from the 230 V power supply.
•
Before you remove the covers, completely isolate the device controller
from the power supply.
•
Verify that the main circuit board is voltage-free.
Fusing is provided on the I/O module's main circuit board.
