Safety information

Commissioning must 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 S120 Cabinet Modules 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.
Operational electrical equipment and motors have parts and components which are at
hazardous voltage levels.
When the machine or system is operated, hazardous axis movements can occur.
All work on the electrical system must be carried out when the system has been
disconnected from the power supply and is in a de-energized condition.
When carrying out any kind of work on electrical devices, the following "five safety rules"
must always be observed:
• Disconnect from power supply.
• Protect against reconnection.
• Make sure that the equipment is de-energized.
• Ground and short-circuit.
• Cover or enclose adjacent components that are still live.
Safe, problem-free operation of SINAMICS S120 Cabinet Modules requires proper
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 plant-specific regulations and
requirements must be taken into account.
Only protective extra-low voltages (PELVs) that comply with EN 60204-1 may be connected
to any connections and terminals between 0 and 48 V.
