Protection Against Magnetic and Electromagnetic Fields During Oper‐
ation and Mounting
WARNING
1.1.5
Protection Against Contact With Hot Parts
CAUTION
Magnetic and electromagnetic fields generated by current-carrying conductors
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
hearing 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 systems
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 greatly so 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 sufficiently long 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 according to the respective safety regulations,
the manufacturer of the machine or installation has to take measures to
avoid injuries caused by burns in the end application. These measures
can be, for example: Warnings at the machine or installation, guards
(shieldings or barriers) or safety instructions in the application documen‐
tation.
