If the device is linked to other devices and/or equipment, consider the impacts and
take appropriate precautions before switching it off.
The protective conductor connection in the respective device carrier must be
connected to the protective conductor (for devices with protection class I).
Warning of personal injury and property damage!
Any interruption of the protective earth in the equipment carrier can result

2.3.5 Troubleshooting
At the beginning of troubleshooting, all possible sources of faults on additional devices or
supply lines (measuring lines, wiring and downstream devices) should be taken into

Do not open the device when it is connected to the voltage! When
opening the devices or removing covers and parts, live parts may be
exposed. Connection points can also be live!
