Figure 15: Option locations on the connection unit
The various installation locations for the optional modules are displayed in the above-mentioned
drawings. Option location 1 is used for implementation of an internal bus module or an internal power
supply (not SK 2x0E). An internal brake resistor can be implemented at option location 2. External bus
modules, 24 V DC power supplies (not SK 2x0E) or potentiometer modules can be fitted at option
location 3L or 3R. The same applies to external brake resistors. Option locations 4 and 5 are used to
install M12 sockets or connectors. Additional extensions from M12 to M16 are required at locations 6,
7 and 8 for sizes 1 to 3 so that M12 sockets and connectors can also be fitted here. Option locations 6
- 8 are also M16 for size 4 devices. Only one option can be attached in an option location, of course.
