Siemens SIMOTICS L-1FN3 - Technical Features

• To free jammed parts of the body (e.g. hands, 󹪝ngers, feet), pull apart components that are
clamped together.
– Do this using the non-magnetic hammer to drive the non-magnetic wedges into the
separating rift.
– Release the jammed body parts.
• If necessary, call the emergency medical service or an emergency physician.
Material damage caused by strong magnetic 󹪝elds
NOTICE
Data loss caused by strong magnetic 󹪝elds
If you are close to a secondary section (< 150 mm) any magnetic or electronic data medium as
well as electronic devices that you are carrying can be destroyed. For example, credit cards, USB
sticks, 󹪞oppy disks and watches are at risk.
• Do not carry any magnetic/electronic data media and no electronic devices when you are
close to a secondary section!
