4.2.3 Voltage measurement output
You can check the supply voltages manually at the voltage measurement output, for example using a
multimeter.
An unsuitable measuring device can falsify the measurement.
The measurement will be falsified if the input resistance of the connected measuring device is too
small.
• Use a measuring device that meets the requirements in the technical data [
}
10] .
The measurement output cannot be used as a supply voltage output
The output voltages will collapse if they are loaded.
• Do not use the measurement output as a supply voltage output.
If you wish to decouple the supply voltages from an EtherCAT P signal, use an EPP9001-0060 ,
for example.
