7.1 Magnetic field when the brake is open
WARNING
Magnetic field when the holding brake is open
If the motor is equipped with a holding brake, then the shaft extension is magnetized when
the holding brake is open, i.e. if a voltage is connected to it.
Magnetic objects will then be suddenly attracted as a result of this magnetic field. This can
result in death, severe injury or material damage.
Working close to the shaft extension is only permissible in exceptional, justified cases.
Clear access rules must be applied and complied with corresponding to magnetic fields
at 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 occupational health 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. drilling threaded holes. Any exceptions
require written approval from the manufacturer.
