5 Work and safety instructions

General
Trainees should only work with the circuits under the supervision of an instructor.
Observe the specifications included in the data sheets and operating instructions for the individual
components, and in particular all safety instructions!
Malfunctions which may impair safety must not be generated.
Wear personal safety equipment (safety glasses, hearing protection, safety shoes) when working on
circuits.
Electrical system
Disconnect from all sources of electrical power!
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 respective components.
Use extra-low voltage only: max. 24 V DC.
Establishing and disconnecting electrical connections
Electrical connections may only be established in the absence of voltage.
Electrical connections may only be disconnected in the absence of voltage.
Maximum permissible current loads for cables and devices must not be exceeded.
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.
Use only connecting cables with safety plugs for electrical connections.
When laying connecting cables, make sure they are not kinked or pinched.
Do not lay cables over hot surfaces.
Hot surfaces are identified with a corresponding warning symbol.
Make sure that connecting cables are not subjected to continuous tensile loads.
Devices with an earth terminal must always be grounded.
If an earth connection (green-yellow laboratory socket) is available, it must always be
connected to protective earth. Protective earth 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 protective earth conductor.
The device is not equipped with an integrated fuse unless specified otherwise in the technical data.
Always pull on the plug when disconnecting connecting cables; never pull the cable.
