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.
–
•
Make sure that connecting cables are not subjected to continuous tensile loads.
•
Devices with a ground connection must always be grounded.

•
When replacing fuses, use specified fuses only with the correct current rating and
tripping characteristics.

The device is not equipped with an integrated fuse unless otherwise specified in the
technical data.
•
Pull the safety plug only when disconnecting connecting cables; never pull the
cable.

Electrical connections may only be established in the absence of voltage.
Electrical connections may only be interrupted in the absence of voltage.
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.
Hot surfaces are identified with a corresponding warning symbol.
If a ground connection (green and yellow laboratory socket) is available, it must
always be connected to protective ground. The protective ground must always
be connected first (before connecting voltage), and must always be
disconnected last (after disconnecting voltage).
Some devices have high leakage current. These devices must be additionally
grounded with a protective grounding conductor.

malfunction,
inappropriate storage, or
incorrect transport.
Switch off the power supply immediately.
Protect the device against inadvertent restart.
