Removing a BaseUnit
WARNING
Hazardous Voltage
Hazardous electrical voltage can cause electric shock, burns and property damage.
Disconnect your system and devices from the power supply before starting any assembly
tasks.
To remove a BaseUnit, follow these steps:
The BaseUnit is wired and there are other BaseUnits to its right and left.
To remove a specific BaseUnit, move the adjacent modules. As soon as you have created a
clearance of about 8 mm from the adjacent BaseUnits, you can remove the BaseUnit.
Note
You can replace the terminal box without removing the BaseUnit. Refer to section
