Troubleshooting!
At the beginning of troubleshooting, all possible sources of faults on
additional devices or supply lines (measuring lines, wiring, downstream
devices) should be taken into consideration. If the fault is not found after
checking these points, we recommend sending the device to the supplier.
Decommissioning!
Switch off the power supply on all poles if the device is to be
decommissioned. Secure the device against being unintentionally switched
on!
If the device is linked to other devices and/or equipment, consider the
impacts and take appropriate precautions before switching it off.
