Danger notices

The following notices are intended firstly for your personal safety and secondly to prevent
damage occurring to the product described or any connected devices and machines. Non-
observance of the warnings can result in severe personal injury or property damage.
Only appropriately qualified personnel may commission/start-up SINUMERIK equipment.
The personnel must take into account the information provided in the technical customer
documentation for the product, and be familiar with and observe the specified danger and
warning notices.
When electrical equipment and motors are operated, the electrical circuits automatically
conduct a dangerous voltage.
When the system is operating, dangerous axis movements may occur throughout the entire
work area.
A potential fire hazard exists due to the energy being transferred in the equipment and the
work materials used.
All work on the electrical system must be performed after the system has been switched off
and disconnected from the power supply.
Proper transportation, expert storage, installation and mounting, as well as careful opera-
tion and maintenance are essential for this SINUMERIK device to operate correctly and
reliably.
The details in the catalogs and proposals also apply to the design of special equipment
versions.
In addition to the danger and warning information provided in the technical customer docu-
mentation, the applicable national, local, and system-specific regulations and requirements
must be taken into account.
Only protective extra-low voltages (PELVs) that comply with EN 61800-5-1 can be connec-
ted to all connections and terminals between 0 and 48 V.
Should it be necessary to test or take measurements on live equipment, then the specifica-
tions and procedural instructions defined in Accident Prevention Regulation VBG A2 must
be adhered to, in particular § 8 "Permissible deviations when working on live components".
Suitable electric tools should be used.
