Use safety extra-low voltage only: max. 24 V DC.
•
The power supply must only be operated using a power supply with a protective grounding conductor.
•
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 connector cables over hot surfaces.
– Hot surfaces are identified with a corresponding warning symbol.
•
Make sure that connector cables are not subjected to continuous tensile loads.
•
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
