Basics

Introduction
All modules of the ET 200SP distributed I/O system are open equipment. This means you
may only install the ET 200SP distributed I/O system in housings, cabinets or electrical
operating rooms and in a dry indoor environment (degree of protection IP20). 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 met. The
housings, cabinets, and electrical operating rooms must not be accessible without a key or
tool. Personnel with access must have been trained or authorized.
Installation location
Install the ET 200SP distributed I/O system in a suitable enclosure/control cabinet with
sufficient mechanical strength and fire protection. Take into account the environmental
conditions for operating the devices.
Mounting position
You can mount the ET 200SP distributed I/O system in any position. The preferred mounting
position is horizontal mounting on a vertical wall.
The ambient temperature may be restricted in certain installation positions. You will find
more information in the section Mechanical and climatic environmental conditions
(Page 282).
Pay attention to chapter "Installation conditions for motor starters (Page 67)" when using
motor starters.
