Mounting on printed-circuit boards
Mounting on PCBs is only possible with 3-slot holders.
3SU1 devices can be mounted on PCBs using the 3-slot or 4-slot holder.
If the PCB carrier 3SU1900-0KA10-0AA0 is attached to a 4-slot holder, the holder cannot
accommodate an LED module. One position on the 4-slot holder is also left empty.
