2.8.1 Fixing
The Central Controller is designed for installation in a housing or Control cabinet with hat rail provided. Mains
power lines located near low-voltage lines and network connections may cause disturbances. Make sure that
there is sufficient distance and use effective cable management techniques to avoid unintentional issues.
The housing is placed on the hat rail and hooked in. By pulling the locking mechanism (with a screwdriver),
the housing can be removed again.
2.8.2 Removing and adding SD cards.
The firmware of the central controller is stored on the SD card. Before commissioning the central controller
the SD card must be plugged in, this can be verified by a clicking noise. (see arrow)
Do not forcibly pull out the SD card! The SD card and the SD memory card socket may be damaged as
a result.
2.8.3 Electrical Connection
The central controller is the interface between the modbus functionality of the MultiPlexBoxes, and the PC
software installed on the PC connected to the central controller via USB. The electrical connection is covered
in the central controller manual.
