Electrical system

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.

Use protective extra-low voltage only: max. 24 V dc.

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.
– If 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 high leakage current. These devices must be additionally grounded
with a protective earth conductor.

The device is not equipped with an integrated fuse unless specified otherwise in the technical data.

Always pull on the safety plug when disconnecting connecting cables – never pull the cable.
