WARNING
Spread of re from built-in devices
Built-in devices can cause a re and a pressure wave in the event of a fault. Fire and smoke can
escape from the control cabinet and cause serious personal injury and property damage.
• Install built-in appliances in a robust metal control cabinet that is suitable for protecting
people from re and smoke.
• Only operate built-in devices with the control cabinet doors closed.
• Ensure that smoke can only escape via controlled and monitored paths.
CAUTION
Symptomatic respiratory and skin reaction to chemicals
A newly purchased product might contain traces of substances that are identied as sensitizers.
Sensitizers are substances which can cause sensitization in the lungs and skin after exposure
to them.
Once sensitized, individuals can have severe reactions to further exposure, even in small
amounts. In the most extreme cases, individuals might develop asthma or dermatitis
respectively.
• If the product has a strong smell, keep it in a well-ventilated area for 14 days.
WARNING
Unexpected machine movement caused by radio devices or mobile phones
Using radio devices, cellphones, or mobile WLAN devices in the immediate vicinity of the
components can result in equipment malfunction. Malfunctions may impair the functional
safety of machines and can therefore put people in danger or lead to property damage.
• Therefore, if you move closer than 20cm to the components, be sure to switch o radio
devices, cellphones or WLAN devices.
• Use the "SIEMENS Industry Online Support App" or a QR code scanner only on equipment
that has already been switched o.
WARNING
Fire due to inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating of components with subsequent re
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 specied minimum clearance as ventilation clearance for the
respective component.
