3.1

Installing S5-100U Components

Except for the I/O module, all of the S5-100U components are mounted on standard mounting rails
in accordance with DIN EN 50022-35x15. Mount the rails on a metal plate to obtain the same
reference potential.
Bus units with a SIGUT/screw-type, or crimp snap-in connection method have different heights.
If you install, remove, or change any parts of your S5-100U system, your system must be in the
state indicated in Table 3-1.

Assembling a Tier

You need the following components to configure the S5-100U:
• Power supply module
• Central processing unit
• Bus units
• I/O modules
If you do not have a 24 V DC power supply, you must have a power supply module.
Mount the first module on the extreme left end of the standard mounting rail. Add other modules to
the right of the first module.
