Important safety notices for Safety Integrated functions
If you want to use Safety Integrated functions, you must
observe the safety notices in the Safety Integrated chapters.
Danger of an accident occurring due to missing or
illegible warning labels
Missing or illegible warning labels can result in accidents
involving death or serious injury.
• Check that the warning labels are complete based on the
documentation.
• Attach any missing warning labels to the components, in
the national language if necessary.
• Replace illegible warning labels.
Danger to life from permanent magnet fields
Even when switched off, electric motors with permanent
magnets represent a potential risk for persons with heart
pacemakers or implants if they are close to
converters/motors.
• If you are such a person (with heart pacemaker or
implant) then keep a minimum distance of 2 m.
• When transporting or storing permanent magnet motors
always use the original packing materials with the warning
labels attached.
• Clearly mark the storage locations with the appropriate
warning labels.
• IATA regulations must be observed when transported by
Injury caused by moving parts or those that are flung
out
Touching moving motor parts or drive output elements and
loose motor parts that are flung out (e.g. feather keys) in
operation can result in severe injury or death.
• Remove any loose parts or secure them so that they
cannot be flung out.
• Do not touch any moving parts.
• Safeguard all moving parts using the appropriate safety
Danger to life due to fire as a result of overheating
caused by incorrect operation
When incorrectly operated and in the case of a fault, the
motor can overheat resulting in fire and smoke. This can
result in severe injury or death. Further, excessively high
temperatures destroy motor components and result in
increased failures as well as shorter service lives of motors.
• Operate the motor according to the relevant
specifications.
• Only operate the motors in conjunction with effective
temperature monitoring.
• Immediately switch off the motor if excessively high
Risk of injury due to touching hot surfaces
In operation, the motor can reach high temperatures, which
can cause burns if touched.
• Mount the motor so that it is not accessible in operation.
• When maintenance is required allow the motor to cool
down before starting any work.
• Use the appropriate personnel protection equipment, e.g.
1.2 Safety instructions for electromagnetic fields (EMF)
Danger to life from electromagnetic fields
Electromagnetic fields (EMF) are generated by the
operation of electrical power equipment such as
transformers, converters or motors.
People with pacemakers or implants are at a special risk in
the immediate vicinity of these devices/systems.
• Ensure that the persons involved are the necessary
distance away (minimum 2 m).
1.3 Handling electrostatic sensitive devices (ESD)
Electrostatic sensitive devices (ESD) are individual components,
integrated circuits, modules or devices that may be damaged by either
electric fields or electrostatic discharge.
Damage through electric fields or electrostatic
discharge
Electric fields or electrostatic discharge can cause
malfunctions through damaged individual components,
integrated circuits, modules or devices.
• Only pack, store, transport and send electronic
components, modules or devices in their original
packaging or in other suitable materials, e.g conductive
foam rubber of aluminum foil.
• Only touch components, modules and devices when you
are grounded by one of the following methods:
− Wearing an ESD wrist strap
− Wearing ESD shoes or ESD grounding straps in ESD
areas with conductive flooring
• Only place electronic components, modules or devices
on conductive surfaces (table with ESD surface,
conductive ESD foam, ESD packaging, ESD transport
1.4 Residual risks of power drive systems
Residual risks of power drive systems
The control and drive components of a drive system are approved for
industrial and commercial use in industrial line supplies. Their use in
public line supplies requires a different configuration and/or additional
measures.
These components may only be operated in closed housings or in
higher-level control cabinets with protective covers that are closed,
and when all of the protective devices are used.
These components may only be handled by qualified and trained
technical personnel who are knowledgeable and observe all of the
safety instructions on the components and in the associated technical
user documentation.
When assessing the machine's risk in accordance with the respective
local regulations (e.g., EC Machinery Directive), the machine
manufacturer must take into account the following residual risks
emanating from the control and drive components of a drive system:
1. Unintentional movements of driven machine components during
commissioning, operation, maintenance, and repairs caused by,
for example,
- Hardware and/or software errors in the sensors, control system,
actuators, and cables and connections
- Response times of the control system and of the drive
- Operation and/or environmental conditions outside the
specification
- Condensation/conductive contamination
- Parameterization, programming, cabling, and installation errors
- Use of wireless devices/mobile phones in the immediate vicinity
of the control system
- External influences/damage
2. In the event of a fault, exceptionally high temperatures, including
an open fire, as well as emissions of light, noise, particles, gases,
etc. can occur inside and outside the drive, e.g.:
- Component failure
- Software errors
- Operation and/or environmental conditions outside the
specification
- External influences/damage
Drives of the Open Type/IP20 degree of protection must be
installed in a metal control cabinet (or protected by another
equivalent measure) such that contact with fire inside and outside
the drive is not possible.
3. Hazardous shock voltages caused by, for example,
- Component failure
- Influence during electrostatic charging
- Induction of voltages in moving motors
- Operation and/or environmental conditions outside the
specification
- Condensation/conductive contamination
- External influences/damage
