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.
