• 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 to ensure that they match.
– 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 indicated by a corresponding warning symbol.
• Make sure that connecting cables are not subjected to continuous tensile loads.
• The device is not equipped with a built-in fuse unless otherwise specified in the technical data.
• Pull the plug only when disconnecting connecting cables; never pull the cable.
• Hazard-free operation of the device is no longer possible in the case of:
– Visible damage
– Malfunction
– Incorrect storage
– Incorrect transport.
– Switch off the power supply immediately.
– Protect the device against an inadvertent restart.
5.4 Pneumatics
• Depressurize the system.
– Switch off the compressed air supply before working on the circuit.
– Use pressure gauges to check whether the entire circuit is pressure-free.
– Please note that energy may be stored in reservoirs.
Information on this issue is available in the datasheets and operating instructions included
with the components.
• Do not exceed the maximum permissible pressure of 6 bar (600 kPa).
• Do not switch on the compressed air until all the tubing connectors have been joined and secured.
• Do not disconnect tubing while under pressure.
• Do not attempt to seal or plug pneumatic tubing or plug connectors with your hands or fingers.
• Risk of injury when switching on compressed air!
Cylinders can advance and retract automatically.
