WARNING
Unexpected movement of machines caused by radio devices or mobile phones
When radio devices or mobile phones with a transmission power > 1 W are used in the
immediate vicinity of components, they may cause the equipment to malfunction.
Malfunctions may impair the functional safety of machines and can therefore put people in
danger or lead to property damage.
•
If you come closer than around 2 m to such components, switch off any radios or mobile
phones.
•
Use the "SIEMENS Industry Online Support app" only on equipment that has already
been switched off.
NOTICE
Damage to motor insulation due to excessive voltages
When operated on systems with grounded line conductor or in the event of a ground fault in
the IT system, the motor insulation can be damaged by the higher voltage to ground. If you
use motors that have insulation that is not designed for operation with grounded line
conductors, you must perform the following measures:
•
IT system: Use a ground fault monitor and eliminate the fault as quickly as possible.
•
TN or TT systems with grounded line conductor: Use an isolating transformer on the line
side.
WARNING
Fire due to inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating of components with subsequent
fire and smoke. This can cause severe injury or even death. This can also result in
increased downtime and reduced service lives for devices/systems.
•
Ensure compliance with the specified minimum clearance as ventilation clearance for
the respective component.
NOTICE
Overheating due to inadmissible mounting position
The device may overheat and therefore be damaged if mounted in an inadmissible position.
•
Only operate the device in admissible mounting positions.
WARNING
Unrecognized dangers due to missing or illegible warning labels
Dangers might not be recognized if warning labels are missing or illegible. Unrecognized
dangers may cause accidents resulting in serious injury or death.
•
Check that the warning labels are complete based on the documentation.
•
Attach any missing warning labels to the components, where necessary in the national
language.
•
Replace illegible warning labels.
