•
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.
•
When replacing fuses, use specified fuses only with the correct current ratings and tripping
characteristics.
•
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.
•
Hazard-free operation of the device is no longer possible in the case of:
– Visible damage
– Malfunction
– Incorrect storage
– Incorrect transport
– Switch off the power supply immediately.
– Protect the device against inadvertent restart.
