PROFINET with Ethernet-APL
The reference cable type for APL segments is fieldbus cable type A, MAU type 1 and 3
(specified in IEC 61158-2). This cable meets the requirements for intrinsically safe
applications according to IEC TS 60079-47 and can also be used in non-intrinsically safe
applications.
Cable type A
Cable capacitance 45 to 200 nF/km
Loop resistance 15 to 150 Ω/km
Cable inductance 0.4 to 1 mH/km
Further details are provided in the Ethernet-APL Engineering Guideline
(https://www.ethernet-apl.org).
6.2.3 Overvoltage protection
The overvoltage protection can optionally be ordered as a "Mounted accessory" via the
product structure
Devices without optional overvoltage protection
The equipment 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
