normal use. It might possibly be necessary to perform a special electro‐
magnetic compatibility (EMC) test.
Magnetic and electromagnetic fields generated by current-carrying conduc‐
tors or permanent magnets of electric motors represent a serious danger to
persons with heart pacemakers, metal implants and hearing aids.
Health hazard for persons with heart pacemakers, metal implants and hear‐
ing aids in proximity to electric components!
● Persons with heart pacemakers and metal implants are not allowed to
enter the following areas:
– Areas in which components of the electric drive and control sys‐
tems are mounted, commissioned and operated.
– Areas in which parts of motors with permanent magnets are stored,
repaired or mounted.
● If it is necessary for somebody with a heart pacemaker to enter such an
area, a doctor must be consulted prior to doing so. The noise immunity
of implanted heart pacemakers differs so greatly that no general rules
can be given.
● Those with metal implants or metal pieces, as well as with hearing aids,
must consult a doctor before they enter the areas described above.
Hot surfaces of components of the electric drive and control system. Risk of
burns!
● Do not touch hot surfaces of, for example, braking resistors, heat sinks,
supply units and drive controllers, motors, windings and laminated
cores!
● According to the operating conditions, temperatures of the surfaces can
be higher than 60 °C (140 °F) during or after operation.
● Before touching motors after having switched them off, let them cool
down for a sufficient period of time. Cooling down can require up to 140
minutes! The time required for cooling down is approximately five times
the thermal time constant specified in the technical data.
● After switching chokes, supply units and drive controllers off, wait 15 mi‐
nutes to allow them to cool down before touching them.
● Wear safety gloves or do not work at hot surfaces.
● For certain applications, and in accordance with the respective safety
regulations, the manufacturer of the machine or installation must take
measures to avoid injuries caused by burns in the final application.
These measures can be, for example: Warnings at the machine or in‐
stallation, guards (shieldings or barriers) or safety instructions in the ap‐
plication documentation.
Risk of injury by improper handling! Injury by crushing, shearing, cutting, hit‐
ting!
