1) Allow for particular module widths; additional slots to the right may be occupied (see Catalog ST 54.1).
2) In the CC with Order No. 6ES5 135-3UA41, only at Slot 163
3) Observe jumper setting on the IM 307; interrupt transmission is only possible at Slots 107 to 131.
4) Operation at Slots 27, 43, 59, 139, 147 is only possible with severely restricted functions, because no interrupts are wired.

The housing consists of bolted sheet-steel sections with ventilation
openings at the top and bottom. The housing contains the bus PCB for
electrical and logical interconnection of the modules. All the slots
have guiderails which accept the modules. Male and female
connectors are thus precisely positioned. There is a locking bar at the
top of the housing to prevent the modules from becoming accidentally
detached. Modules with individual locking are secured in the lower
sectional rail. There is a cable duct for incoming and outgoing cables
at the front of the housing.
The power supply unit with the fans is situated in the lower part of the
central controller frame. Depending on the type of power supply, the
input voltage is either 24 V DC or 230/120 V AC. The AC version can
be adjusted to the required AC voltage with a selector switch.
The following table shows which modules can be inserted at which
slots.
