Fundamental safety instructions 2
2.1 General safety instructions
WARNING
Electric shock and danger to life due to other energy sources
Touching live components can result in death or severe injury.
●Only work on electrical devices when you are qualified for this job.
●Always observe the country-specific safety rules.
Generally, the following six steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be affected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time specified on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any of
the power connections and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water. Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness in the inverse sequence.
WARNING
Risk of electric shock and fire from supply networks with an excessively high impedance
Excessively low short-circuit currents can lead to the protective devices not tripping or tripping
too late, and thus causing electric shock or a fire.
● In the case of a conductor-conductor or conductor-ground short-circuit, ensure that the
short-circuit current at the point where the inverter is connected to the line supply at least
meets the minimum requirements for the response of the protective device used.
● You must use an additional residual-current device (RCD) if a conductor-ground short
circuit does not reach the short-circuit current required for the protective device to respond.
The required short-circuit current can be too low, especially for TT supply systems.
Motor Modules Booksize parallel connection
Application Manual, 01/2020, 6SL3097-5BF00-0BP0 9

WARNING
Risk of electric shock and fire from supply networks with an excessively low impedance
Excessively high short-circuit currents can lead to the protective devices not being able to
interrupt these short-circuit currents and being destroyed, and thus causing electric shock or
a fire.
● Ensure that the prospective short-circuit current at the line terminal of the inverter does not
exceed the breaking capacity (SCCR or Icc) of the protective device used.
WARNING
Electric shock if there is no ground connection
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
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may
carry a hazardous voltage. Contact with hazardous voltage can result in severe injury or death.
● 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.
WARNING
Electric shock due to equipment damage
Improper handling may cause damage to equipment. 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.
Fundamental safety instructions
2.1 General safety instructions
Motor Modules Booksize parallel connection
10 Application Manual, 01/2020, 6SL3097-5BF00-0BP0

WARNING
Electric shock due to unconnected cable shield
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
Arcing when a plug connection is opened during operation
Opening a plug connection when a system is operation can result in arcing that may cause
serious 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
Electric shock due to residual charges in power components
Because of the capacitors, a hazardous voltage is present for up to 5 minutes after the power
supply has been switched off. Contact with live parts can result in death or serious injury.
● Wait for 5 minutes before you check that the unit really is in a no-voltage condition and start
work.
NOTICE
Property damage due to loose power connections
Insufficient tightening torques or vibration can result in loose power connections. This can
result in damage due to fire, device defects or malfunctions.
●Tighten all power connections to the prescribed torque.
● Check all power connections at regular intervals, particularly after equipment has been
transported.
WARNING
Spread of fire from built-in devices
In the event of fire outbreak, the enclosures of built-in devices cannot prevent the escape of
fire and smoke. This can result in serious personal injury or property damage.
● Install built-in units in a suitable metal cabinet in such a way that personnel are protected
against fire and smoke, or take other appropriate measures to protect personnel.
● Ensure that smoke can only escape via controlled and monitored paths.

Motor Modules Booksize parallel connection
Application Manual, 01/2020, 6SL3097-5BF00-0BP0 11

WARNING
Active implant malfunctions due to electromagnetic fields
Inverters generate electromagnetic fields (EMF) in operation. Electromagnetic fields may
interfere with active implants, e.g. pacemakers. People with active implants in the immediate
vicinity of an inverter are at risk.
● As the operator of an EMF-emitting installation, assess the individual risks of persons with
active implants.
● Observe the data on EMF emission provided in the product documentation.
WARNING
Unexpected movement of machines caused by radio devices or mobile phones
When radio devices or mobile phones with a transmission power > 1 W are used in the
immediate vicinity of components, they may cause the equipment to malfunction.
Malfunctions may impair the functional safety of machines and can therefore put people in
danger or lead to property damage.
● If you come closer than around 2 m to such components, switch off any radios or mobile
phones.
● Use the "SIEMENS Industry Online Support app" only on equipment that has already been
switched off.
NOTICE
Damage to motor insulation due to excessive voltages
When operated on systems with grounded line conductor or in the event of a ground fault in
the IT system, the motor insulation can be damaged by the higher voltage to ground. If you use
motors that have insulation that is not designed for operation with grounded line conductors,
you must perform the following measures:
● IT system: Use a ground fault monitor and eliminate the fault as quickly as possible.
● TN or TT systems with grounded line conductor: Use an isolating transformer on the line
side.
WARNING
Fire due to inadequate 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.

12 Application Manual, 01/2020, 6SL3097-5BF00-0BP0

NOTICE
Overheating due to inadmissible mounting position
The device may overheat and therefore be damaged if mounted in an inadmissible position.
● Only operate the device in admissible mounting positions.
WARNING
Unrecognized dangers due to missing or illegible warning labels
Dangers might not be recognized if warning labels are missing or illegible. Unrecognized
dangers may cause accidents resulting in serious injury or death.
● Check that the warning labels are complete based on the documentation.
● Attach any missing warning labels to the components, where necessary in the national
language.
●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 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
Unexpected movement of machines caused by inactive safety functions
Inactive or non-adapted safety functions can trigger unexpected machine movements that
may result in 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.
