Protection against magnetic and electromagnetic fields during operation and assembly

Magnetic and electromagnetic fields that surround live conductors and the permanent magnets of motors
can pose a serious risk to persons with pacemakers, metal implants, or hearing aids.
Health risk for persons with pacemakers, metal implants, and hearing aids in
the immediate vicinity of electrical equipment!
Magnetic and electromagnetic fields may interfere with and impair the function of pacemakers or
hearing aids as well as of metal implants. This may lead to a health risk for the persons concerned.

DANGER
Persons with pacemakers and metal implants are prohibited from entering the following areas:
– Areas in which electrical devices and parts are assembled, operated, or commissioned
– Areas in which motor parts with permanent magnets are stored, repaired, or assembled
If persons with pacemakers need to enter these types of areas, a physician must first be con-
sulted. The interference resistance of current or future pacemaker versions varies greatly. For this
reason, no generally applicable rules exist.
Persons with metal implants, metal shrapnel in the body, or hearing aids must consult a physician
before entering these types of areas, as adverse health effects must be expected in these areas.
CAUTION
Do not touch device housing surfaces at heat sources! Risk of burns!
Do not touch housing surfaces of motors and gearboxes! Risk of burns!
Depending on the operating conditions, temperatures during or after operation may exceed
60 °C (140 °F).
After switching off the motors, allow them to cool down sufficiently before accessing them.
Wear protective gloves or do not work near hot surfaces.
For specific applications, the manufacturer must undertake measures on the end product, the
machine, or the system to prevent burn injuries during the end use. These measures must be in
accordance with the safety regulations. Examples of possible measures are: safety warnings, a
separating safety device (shielding or locking), and technical documentation.
