Only using the serially delivered motor holding brake or an external
holding brake activated by the drive controller is not suitable for person‐
al protection!
Rotating parts! Danger to life, risk of injury, heavy injury or material damage.
● Secure key and/or transmission elements against ejection.
● Install covers on dangerous rotating machine parts before start-up.
2.6.3 Protection against magnetic and electromagnetic fields
Magnetic and electromagnetic fields are created in the direct environment of
live conductors or permanent magnets of electro motors and are a serious
danger for persons.
Strong magnetic and electromagnetic fields pose a health hazard for persons
with heart pacemakers, metallic implants and hearing aids in the direct envi‐
ronment of motor components!
● Persons with heart pacemakers and metallic implants are not allowed to
approach or handle these motor components.
Crushing hazard of fingers and hands due to strong attractive forces of the
magnets!
● Handle only with protective gloves.
Risk of destruction of sensitive parts!
● Keep watches, credit cards, check cards and identity cards and all ferro‐
magnetic metal parts, such as iron, nickel and cobalt away from perma‐
nent magnets.
2.6.4 Protection against burns
Risk of burns due to hot motor surfaces!
● Avoid contact with hot motor surfaces. Temperatures may rise to over
70°C.
● Allow the motors to cool down long enough before touching them.
● Temperature-sensitive components may not come into contact with the
motor surface. Ensure appropriate mounting distance of connection ca‐
bles and other components.
