1.1
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 devices when you are qualified for this job.
•Always observe the country-specific safety rules.
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 no-voltage condition, from phase conductor to phase
conductor and phase conductor to protective conductor.
–Check whether the existing auxiliary supply circuits are 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. Secure the energy sources against switching on again.
6. Ensure that the correct machine is completely interlocked.
After you have completed the work, restore the operational readiness in the inverse
sequence.
WARNING
Danger to life through a hazardous voltage when connecting an unsuitable power supply
Touching live components can result in death or severe injury.
•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.

8Operating Instructions, 03/2014, A5E34142527B-AA
WARNING
Danger to life when live parts are touched on damaged devices
Improper handling of devices can cause damage.
For damaged devices, hazardous voltages can be present at the enclosure or at exposed
components; if touched, this can result in death or severe injury.
•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.
•As a minimum, connect cable shields and the conductors of power cables that are not
used (e.g. brake cores) at one end at 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 no-voltage state, unless it has
been explicitly stated that they can be opened in operation.
WARNING
Danger to life due to fire spreading if housing is inadequate
Fire and smoke development can cause severe personal 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 is prevented.
•Ensure that smoke can only escape via controlled and monitored paths.

Chemical industry module CM240NE with CU250S-2 DP
Operating Instructions, 03/2014, A5E34142527B-AA 9
WARNING
Danger to life through unexpected movement of machines when using mobile wireless
devices or mobile phones
Using mobile wireless devices 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.
•Switch the wireless devices or mobile phones off in the immediate vicinity of the
components.
WARNING
Danger to life due to the motor catching fire in the event of insulation overload
There is higher stress on the motor insulation through a ground fault in an IT system. If the
insulation fails, it is possible that death or severe injury can occur as a result of smoke and
fire.
•Use a monitoring device that signals an insulation fault.
•Correct the fault as quickly as possible so the motor insulation is not overloaded.
WARNING
Danger to life due to fire if overheating occurs because of insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating of components with subsequent
fire and smoke. This can cause severe injury or even death. This can also result in
increased downtime and reduced service lives for devices/systems.
•Ensure compliance with the specified minimum clearance as ventilation clearance for
the respective component.
WARNING
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.

1.2 Safety instructions for electromagnetic fields (EMF)
Chemical industry module CM240NE with CU250S-2 DP
10 Operating Instructions, 03/2014, A5E34142527B-AA
NOTICE
Device damage caused by incorrect voltage/insulation tests
Incorrect voltage/insulation tests can damage the device.
•Before carrying out a voltage/insulation check of the system/machine, disconnect the
devices as all converters and motors have been subject to a high voltage test by the
manufacturer, and therefore it is not necessary to perform an additional test within 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 guaranteed that the functions
relevant to safety are running correctly.
Note
Important safety notices for Safety Integrated functions
If you want to use Safety Integrated functions, you must observe the safety no
tices in the
Safety Integrated manuals.
1.2
Safety instructions for electromagnetic fields (EMF)
WARNING
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).
