Safety notes
1.1 Danger notices
Commissioning and operation of the devices
Proper transportation, expert storage, installation and mounting, as well as careful operation
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
documentation, the applicable national, local, and system-specific regulations and
requirements must be taken into account.
Only class DVC A protective extra-low voltages (PELVs) may be connected to connections
and terminals up to 60 V DC in accordance with EN 61800-5-1.
Should it be necessary to test or take measurements on live equipment, then the
specifications and procedural instructions defined in Accident Prevention Regulation BGV
A2 must be adhered to, in particular § 8 "Permissible deviations when working on live
components". Suitable electric tools should be used.
Carrying out of repairs
Repairs to devices that we have supplied may only be carried out by Siemens Customer
Service or by repair centers authorized by Siemens.
When replacing parts or components, only use those parts that are included in the spare
parts list.
EMERGENCY STOP/EMERGENCY OFF devices according to EN 60204-1 (VDE 0113 Part
1) must remain active in all modes of the automation equipment. Resetting the EMERGENCY
STOP/EMERGENCY OFF device must not cause an uncontrolled or undefined restart.
Anywhere in the automation equipment where faults might cause physical injury or major
material damage, in other words, where faults could be dangerous, additional external
precautions must be taken, or facilities must be provided, that guarantee or enforce a safe
operational state, even when there is a fault (e.g. using an independent limit value switch,
mechanical locking mechanisms, EMERGENCY STOP/EMERGENCY OFF devices).
