• Use protective extra-low voltage only: max. 24 V DC.
•
The power pack must only be operated using a power supply with a PE 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.
– Always pull on the plug when disconnecting connecting cables;
never pull the cable.
•
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 a 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.
