•
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 ground connection must always be grounded.
– 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.
•
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 otherwise specified 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.
