Product maintenance
The components are subject to continuous further development within the scope of product
maintenance (improvements to robustness, discontinuations of components, etc.).
These further developments are "spare parts-compatible" and do not change the article
number.
In the scope of such spare parts-compatible further developments, connector positions are
sometimes changed slightly. This does not cause any problems with proper use of the
components. Take this fact into consideration in special installation situations (e.g. allow
sufficient clearance for the cable length).

Generally, the following 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. 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 damaged motors or devices
Improper handling of motors or devices can damage them.
Hazardous voltages can be present at the enclosure or at exposed components on
damaged motors or devices.
•Ensure compliance with the limit values specified in the technical data during transport,
storage and operation.
•Do not use any damaged motors or devices.
WARNING
Electric shock due to unconnected cable shields

•Be sure to only use screwdrivers which exactly match the heads of the screws.
•Tighten the screws with the torque specified in the technical documentation.
•Use a torque wrench or a mechanical precision nut runner with a dynamic torque sensor
and speed limitation system.
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.
