Connections
For a detailed description of the mounting, disassembly and connection of the
module, please refer to the System Assembly chapter
The connection is carried out by using a removable 9-pin terminal block. These terminal blocks
differ in their connection system (spring terminals or screw terminals, cable mounting from the
front or from the side). The terminal blocks are not included in the module's scope of delivery
and must be ordered separately.
