EduTrainer 24 V power supply unit
32
The power pack must only be operated using a power supply with a grounding
conductor.
Establishing and interrupting electrical connections
Electrical connections may only be established in the absence of voltage.
Electrical connections may be interrupted only in the absence of voltage.
Always pull the safety 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.
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 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.
Devices with a ground connection must always be grounded.
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 voltage) and must always be disconnected last (after
disconnecting the voltage).
Some devices have high leakage current. These devices must be fitted with a
grounding conductor (PE conductor) for additional grounding.
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 specified otherwise in the
technical data.
In the event of:
visible damage,
malfunction,
inappropriate storage, or
incorrect transport,
safe operation of the device is no longer possible.
Switch off the power supply immediately.
Protect the device against inadvertent restart.
