Basics

Introduction
All modules of the S7-1500 automation system/ET 200MP distributed I/O system are open
equipment. This means that you may only install this system in housings, cabinets or
electrical operating rooms. The housings, cabinets and electrical operating rooms must
guarantee protection against electric shock and spread of fire. The requirements regarding
mechanical strength must also be observed. The housings, cabinets, and electrical operating
rooms must not be accessible without a key or tool. Access may only be possible for
instructed or authorized personnel.
Installation position
The S7-1500automation system / ET 200MP distributed I/O system can be used in a
horizontal installation for ambient temperatures up to 60 °C and in vertical installation (the
CPU is below) for ambient temperatures up to 40 °C. More information can be found in
chapter Mechanical and climatic ambient conditions (Page 323).
Mounting rail
In addition to the S7-1500/ET 200MP modules, other components can be mounted on the
mounting rail; for example, modules from the S7-1200 and ET 200SP portfolio, terminals,
circuit breakers, small contactors or similar components.
These components can influence the installation dimensions for the cable duct.
Modules can be mounted up to the outer edge of the mounting rail (marginless assembly).
The mounting rails are available in various lengths. You can order the mounting rails using
the online catalog or the online ordering system. You can find the available lengths and
article numbers in the section Accessories/spare parts (Page 335).
