●
The standard equipment motor holding brake or an external holding brake
controlled by the drive controller is not sufficient to guarantee personal
safety!
●
Disconnect electrical power to the components of the electric drive and
control system using the master switch and secure them from reconnec‐
tion ("lock out") for:
–
Maintenance and repair work
–
Cleaning of equipment
–
Long periods of discontinued equipment use
●
Prevent the operation of high-frequency, remote control and radio equip‐
ment near components of the electric drive and control system and their
supply leads. If the use of these devices cannot be avoided, check the
machine or installation, at initial commissioning of the electric drive and
control system, for possible malfunctions when operating such high-fre‐
quency, remote control and radio equipment in its possible positions of
normal use. It might possibly be necessary to perform a special electro‐
magnetic compatibility (EMC) test.
3.3.4
Protection Against Magnetic and Electromagnetic Fields During Oper‐
ation and Mounting
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 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.
3.3.5
Protection Against Contact With Hot Parts
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 mi‐
nutes! The time required for cooling down is approximately five times the
thermal time constant specified in the technical data.
