Safety Information 2.2. Safety in the individual operating phases When installing the control unit and during operation, the following safety instructions must be observed. Danger of Electrocution! Before working on the device, switch off all power supplies used. The electrical cables must be laid according to the respective national regula- tions (in Germany VDE 0100). - Page 8 Technical data Explosion Prevention! The device is suitable for use in explosion zone 22. Before opening the device, it is essential to ensure that no explosive environmental condi- tions, such as dust generation, exist. Troubleshooting! At the beginning of troubleshooting, all possible sources of faults on addi- tional devices or supply lines (measuring lines, wiring, downstream de- vices) should be taken into consideration.
