WARNING
Explosion Hazard!
‣
Please refer to the separate documentation on applications in hazardous areas for the safety
instructions.
For optimum electromagnetic compatibility:
• Keep the potential matching line as short as possible
• Observe a cross-section of at least 2.5 mm

The type of cable entry depends on the device version ordered.
Always route connecting cables downwards so that moisture cannot penetrate the connection
compartment.
If necessary, create a drip loop or use a weather protection cover.

Overvoltage protection
The overvoltage protection can optionally be ordered as a "Mounted accessory" via the product
structure
Devices without optional overvoltage protection
Equipment from Endress+Hauser fulfills the requirements of the product standard IEC / DIN EN
61326-1 (Table 2 Industrial Environment).
Depending on the type of port (DC power supply, input/output port) different testing levels according
to IEC / DIN EN 61326-1 against transient overvoltages (Surge) are applied (IEC / DIN EN
61000-4-5 Surge):
Test level on DC power ports and input/output ports is 1 000 V line to earth
Devices with optional overvoltage protection
• Spark-over voltage: min. 400 V
DC
• Tested according to IEC / DIN EN 60079-14 sub chapter 12.3 (IEC / DIN EN 60060-1 chapter 7)
• Nominal discharge current: 10 kA
