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

2.5
Residual risks of power drive systems
The control and drive components of a drive system are approved for industrial and
commercial use in industrial line supplies. Their use in public line supplies requires a
different configuration and/or additional measures.
These components may only be operated in closed housings or in higher-level control
cabinets with protective covers that are closed, and when all of the protective devices are
used.
These components may only be handled by qualified and trained technical personnel who
are knowledgeable and observe all of the safety instructions on the components and in the
associated technical user documentation.
When assessing the machine's risk in accordance with the respective local regulations (e.g.,
EC Machinery Directive), the machine manufacturer must take into account the following
residual risks emanating from the control and drive components of a drive system:
1. Unintentional movements of driven machine components during commissioning,
operation, maintenance, and repairs caused by, for example,
–Hardware and/or software errors in the sensors, control system, actuators, and cables
and connections
–Response times of the control system and of the drive
–Operation and/or environmental conditions outside the specification
–Condensation/conductive contamination
–Parameterization, programming, cabling, and installation errors
–Use of wireless devices/mobile phones in the immediate vicinity of the control system
–External influences/damage
2. In the event of a fault, exceptionally high temperatures, including an open fire, as well as
emissions of light, noise, particles, gases, etc. can occur inside and outside the inverter,
e.g.:
–Component failure
–Software errors
–Operation and/or environmental conditions outside the specification
–External influences/damage
Inverters of the Open Type/IP20 degree of protection must be installed in a metal control
cabinet (or protected by another equivalent measure) such that contact with fire inside
and outside the inverter is not possible.
