Switch off the power supply before working on the circuit.
Please note that electrical energy may be stored in individual components.
Further information on this issue is available in the data sheets and operating
instructions included with the components.
Caution!
Capacitors inside the device may still be charged even after being disconnected
from all sources of voltage.
Electrical connections may only be established in the absence of voltage.
Electrical connections may only be disconnected in the absence of voltage.
Always pull on the plug when disconnecting connecting cables; never pull the
cable.
Always compare the current ratings of the device, the cable and the fuse.
In the event that these are not the same, use a separate upstream fuse in order
to provide appropriate overcurrent protection.
Hot surfaces are identified with a corresponding warning symbol.
If a grounding terminal (green-yellow laboratory socket) is available, it must
always be connected to the protective grounding. The protective grounding
must always be connected first (before voltage) and must always be
disconnected last (after voltage).
Some devices have a high leakage current. These devices must be additionally
grounded with a PE conductor.
