Derating of the input currents
The table below shows the maximum permissible input current of the distributed I/O systems
depending on the ambient temperature.
Table 7-2 Deratings of the input currents while maintaining the minimum clearance
Ambient temperature
40 °C
50 °C
60 °C
NOTE
Adherence to the minimum clearance
The I/O devices may be used at an installation distance of 2 cm up to max. 60 °C ambient
temperature.
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 must also be taken
into consideration for the derating diagrams of the device manuals.
7.6 Wiring
Wiring
Connect all cables to the front side of the I/O device:
• Supply voltage to the 4-pin M12-L coded round connectors and round sockets
• Signal lines to the 5-pin M12-A coded round sockets
• PROFINET I/O / MultiFieldbus lines on the 4-pin M12-D coded round sockets
Requirement
Wire the I/O devices with the supply voltage off.
Use in hazardous areas
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 specified in the AUTOHOTSPOT section apply for installation.
Required tools
If you are not using pre-assembled cables, you need the following tools:
• Stripping tool
• Screwdriver to wire the connection plugs
