Safety guidelines
Danger
Commissioning shall not start until you have ensured that the machine in which the
components described here are to be installed complies with Directive 98/37/EC.
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 observe the specified danger and
warning notices.
When electrical equipment and motors are operated, the electrical circuits automatically
conduct a dangerous voltage.
Dangerous mechanical movements may occur in the system during operation.
All work on the electrical system must be performed after the system has been switched off
and disconnected from the power supply.
SINAMICS S equipment with three-phase motors may only be connected to the line system
via residual current devices (RCDs) if compatibility of the SINAMICS equipment with the
RCD has been ensured as specified in EN 50178, Subsection 5.2.11.2.
Warning
Correct and safe operation of SINAMICS S equipment assumes correct transportation,
storage, 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 system-specific regulations and
requirements must be taken into account.
Only protective extra-low voltages (PELVs) that comply with EN60204-1 must be connected
to all connections and terminals between 0 and 48 V.
