WARNING
Strong magnetic field when the machine is open
A strong magnetic field is always present inside the machine. If the housing is open, e.g.
when maintenance openings are open or when working inside the machine, magnetic objects
can be suddenly attracted by this magnetic field. This can result in death, severe injury or
material damage.
Working in the vicinity of the rotor is only permitted in exceptional circumstances.
Unambiguous access rules must be established in accordance with the magnetic fields
prevailing in the workplace. Clearly mark the boundaries of the areas where standing is
permitted.
People who need to use electronic or magnetic medical aids such as pacemakers, hearing
aids, implants or similar devices, are at particularly high risk. Such persons must undergo an
industrial medicine assessment.
Observe the following measures.
Personal protective measures
● Ensure that you never wear or carry any of the following objects and that they are kept a
safe distance from the machine:
– All kinds of magnetic metal parts such as, keys, glasses, tools, knives, scissors, tape
measures, etc.
– Magnetic jewelry such as rings, chains, needles, watches, etc.
– Electronic devices and data carriers such as service cards, check cards, credit cards,
calculators, cell phones, etc.
– Wallets or other iron-containing objects
– Electrically conductive foreign bodies
● Do not use any magnetic tools or lifting devices.
● Wear only occupational safety items without magnetic metal parts, e.g. occupational safety
shoes with non-magnetic protective caps and soles.
● Keep your shoes and clothing free from chips and waste containing iron.
● Exercise caution when installing accessories. Ensure that no parts fall into the inside of the
machine.
● Do not perform any cutting at the machine, e.g. manufacturing threaded holes. Any
exceptions require written approval from the manufacturer.
