Preface
Safety information
SINAMICS S equipment must only be commissioned by suitably qualified personnel.
The personnel must take into account the information provided in the technical customer
documentation for the product, and be familiar with and follow the specified danger and
warning notices.
When electrical equipment and motors are operated, the electrical circuits automatically
conduct a dangerous voltage.
Dangerous mechanical movements of the driven machine components are possible during
system operations.
All work on the electrical system must be carried out when the system has been
disconnected from the power supply and is in a no-voltage condition.
Five safety rules
When carrying out any kind of work on electrical devices, the "five safety rules" according to
EN 50110 must always be observed:
1. Disconnect the system.
2. Protect against reconnection.
3. Make sure that the equipment is de-energized.
4. Ground and short-circuit.
5. Cover or enclose adjacent components that are still live.
Correct and safe operation of SINAMICS S units assumes correct transportation in the
transport packaging, correct long-term storage in the transport packaging, setup and
installation, as well as careful operation and maintenance.
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 plant-specific regulations and
requirements must be taken into account.
According to EN 61800-5-1 and UL 508, only safely isolated protective extra-low voltages
on the electronic modules may be connected to any of the terminals on the electronic
modules.
Note
When operated in dry operating areas, SINAMICS equipment with AC motors conforms to
Low-Voltage Directive 2006/95/EC.
