In theory, the control box can be placed anywhere. However, it is recommended to position it in an easily accessible location, typically behind a beam cover. These beam covers are located on the side beams (perpendicular to the back beam where the motor is installed).
It's important to note that the power cord (X103) is 6 meters long. This length may influence the placement depending on where your power outlet is located.
The power can run through any of the four posts, providing flexibility in where the cord and control box are situated.
