Fundamental safety instructions

1.1
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.

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 that might result in serious 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.

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.
WARNING
Active implant malfunctions due to electromagnetic fields
Inverters generate electromagnetic fields (EMF) in operation. People with active implants in
the immediate vicinity of this equipment are at particular risk.
•As the operator of an EMF-emitting installation, assess the individual risks of persons
with active implants. The following clearances are usually adequate:
–No clearance to closed control cabinets and shielded MOTION-CONNECT supply
cables
–Forearm length (approx. 35 cm clearance) to distributed drive systems and open
control cabinets
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.
