Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

General safety instructions
DANGER
Danger to life due to live parts and other energy sources
Death or serious injury can result when live parts are touched.
•Only work on electrical equipment if you are appropriately qualified.
•Always observe the country-specific safety rules for all work.
Generally, six steps apply when establishing safety:
1. Prepare for shutdown and notify all those who will be affected by the procedure.
2. Disconnect the machine from the supply.
–Switch off the machine.
–Wait until the discharge time specified on the warning labels has elapsed.
–Check that it really is in a zero-voltage state, from phase conductor to phase
conductor and phase conductor to protective conductor.
–Check that every auxiliary circuit is de-energized.
–Ensure that the motors cannot move.
3. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems or
water.
4. Isolate or neutralize all hazardous energy sources by closing switches, grounding or
short-circuiting or closing valves, for example.
5. Take measures to prevent reconnection of the energy sources.
6. Make sure that the machine is completely locked ... and that you have the right
machine.
After you have completed the work, restore the operational readiness by following the
above steps in the reverse order.
WARNING
Danger to life through a hazardous voltage when connecting an unsuitable power supply
Death or serious injury can result when live parts are touched in the event of a fault.
•Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV
(Protective Extra Low Voltage) output voltages for all connections and terminals of the
electronics modules.

18 Manual, 10/2015, A5E37067587A
WARNING
Danger to life when live parts are touched on damaged devices
Improper handling of devices can cause damage.
Hazardous voltages can be present at the housing or exposed components on damaged
devices.
•Ensure compliance with the limit values specified in the technical data during transport,
storage and operation.
•Do not use any damaged devices.
WARNING
Danger to life through electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
•Connect cable shields and unused conductors of power cables (e.g. brake conductors)
at least on one side to the grounded housing potential.
WARNING
Danger to life due to electric shock when not grounded
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when
touched, can result in death or severe injury.
•Ground the device in compliance with the applicable regulations.
WARNING
Danger to life due to electric shock when opening plug connections in operation
When opening plug connections in operation, arcs can result in severe injury or death.
•Only open plug connections when the equipment is in a voltage-free state, unless it has
been explicitly stated that they can be opened in operation.
WARNING
Danger to life due to fire spreading if the housing is inadequate
Fire and smoke can cause severe injury or material damage.
•Install devices without a protective housing in a metal control cabinet (or protect the
device by another equivalent measure) in such a way that contact with fire inside and
outside the device is prevented.
•Additionally, select the installation site so that an uncontrolled spreading of smoke can
be avoided in the case of a fire.
•Ensure that smoke can escape via designated paths.

Manual, 10/2015, A5E37067587A 19
WARNING
Danger to life through unexpected movement of machines when using mobile wireless
devices or mobile phones
Using mobile radios or mobile phones with a transmit power > 1 W closer than approx. 2 m
to the components may cause the devices to malfunction, influence the functional safety of
machines therefore putting people at risk or causing material damage.
•When close to components, switch off all wireless devices and mobile phones.
WARNING
Danger to life due to the motor catching fire in the event of insulation overload
There is a greater load on the motor insulation as a result of a ground fault in an IT system.
A possible result is the failure of the insulation with a risk for personnel as a result of fire
and smoke.
•Use a monitoring device that signals an insulation fault.
•Correct the fault as quickly as possible so the motor insulation is not stressed.
WARNING
Danger to life due to fire if overheating occurs because of insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel as a
result of fire and smoke. This can also result in increased downtime and reduced service
lives for devices/systems.
•Ensure compliance with the specified minimum clearances as ventilation clearance for
the respective component. They can be found in the dimension drawings or in the
"Product-specific safety instructions" at the start of the respective section.
WARNING
Risk of an accident due to missing or illegible warning labels
Missing or illegible warning labels can result in 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.

NOTICE
Device damage caused by incorrect voltage/insulation tests
Incorrect voltage/insulation tests can damage the device.
•Before carrying out a voltage/insulation test, disconnect the system/machine.
All converters and motors are subject to a high voltage test in the manufacturer's facility.
As a consequence, it is not necessary to carry out additional tasks in the system/machine.
WARNING
Danger to life when safety functions are inactive
Safety functions that are inactive or that have not been adjusted accordingly can cause
operational faults on machines that could lead to serious injury or death.
•Observe the information in the appropriate product documentation before
commissioning.
•Carry out a safety inspection for functions relevant to safety on the entire system,
including all safety-related components.
•Ensure that the safety functions used in your drives and automation tasks are adjusted
and activated through appropriate parameterizing.
•Perform a function test.
•Only put your plant into live operation once you have absolutely guaranteed that the
functions relevant to safety are operating correctly.
Note
Important safety notices for safety functions
If you want to use safety functions, you must observe the safety notices in the safety
manuals.
