•
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 components.
•
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 connector cables and devices must not be exceeded.
– Always compare the current ratings of the device, the connector 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 connector 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.
•
Device ventilation slots must not be covered! The devices must be hung in A4 mounting frames or
placed on hard, flame-resistant surfaces so that air can flow into them unhindered. The devices are
cooled primarily by convection.
• The device is not equipped with an integrated fuse unless specified otherwise in the technical data.
•
Always pull on the plug when disconnecting connector 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.
Caution
The device may only be operated with safety extra-low voltage (SELV/PELV circuits).
