Inspections In The Event Of Faults - Siemens SIMOTICS SD Operating Instructions Manual

Danger as a result of stationary parts under voltage (live parts)
Live parts represent a hazard. Touch protection against active (live) parts is no longer
guaranteed if covers are removed. The minimum air and creepage distances may be fallen below
(violated) when coming close to active parts. Touching or coming close can result in death,
serious injury or material damage.
• Carefully ensure that all of the covers are closed while operational.
• First switch off and disconnect the machine if you must remove covers. Carefully comply with
the "5 safety rules" (Page 19).
• In operation, the terminal box must always be kept closed. It is only permissible to open the
terminal box when the motor is stationary and in a no voltage condition.
Danger when cleaning using compressed air
When cleaning parts of the machine using compressed air, loose parts or particles of dirt can be
flung around and cause injury.
• Installed suitable extraction measures.
• Wear personal protective equipment, such as protective glasses, gloves, overall.
• Ensure that personnel not involved in the work are not in the danger area.
Damage if the machine is not maintained
The machine can be damaged if it is not appropriately maintained. This can cause faults which
can result in eventual or immediate death, serious injury or material damage.
• Maintain the machine at the specified maintenance intervals.
Damage from foreign bodies in the machine
Foreign bodies such as dirt, tools or loose components can be left by accident inside the machine
after maintenance is performed. These can cause short circuits, reduce the performance of the
cooling system or increase noise in operation. They can also damage the machine.
• Ensure that no foreign bodies are left in or on the machine.
• Securely attach all loose parts once you have completed the work.
• Carefully remove any dirt.
