If you opt for installation on a single rack, insert a dummy module to the right of the
CPU (order no.: 6ES7 370-0AA01-0AA0). This gives you the option of inserting a
second rack for your application in the future, simply by replacing the dummy
module with an interface module and without having to reinstall and rewire the first
rack.

The following rules apply to single-rack module installations:
• No more than eight modules (SM, FM, CP) may be installed to the right of the
CPU.
• All modules mounted on a rack must not consume more than a total of 1.2 A
from the S7-300 backplane bus.
