Basics

Introduction
All ET 200eco PN M12‑L distributed I/O devices are designed for IP65/IP67 and IP69K degrees
of protection. This means that you can directly mount these I/O devices in your plant. Only
use such accessories which are permitted for the required degree of protection.
Mounting position
You can mount the ET 200eco PN M12‑L distributed I/O devices in any mounting position.
Minimum clearances
Ensure that the I/O devices are installed with a minimum clearance of 2 cm.
If the installation distance to other devices or objects is less than 2 cm, the ambient
temperature must be reduced by 5 K (for example, 60 °C ⇒ 55 °C). This also applies to the
derating diagrams in the equipment manuals.
The plug cover is an accessory for protecting the connected connectors on the I/O device. The
plug cover may be necessary for use in hazardous areas. If you use the plug cover, the
minimum distances from section AUTOHOTSPOT apply.
