S7-300 Programmable Controller Hardware and Installation

Recommended procedure - Part I: Hardware
Due to the modular structure and many expansion options, an S7-300 can be quite
extensive and complex. It is therefore inappropriate to initially start up an S7-300
with multiple module racks and all inserted (installed) modules. Rather, we
recommend a step-by-step commissioning procedure.
We recommend the following initial commissioning procedure for an S7-300:
