Safety information

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.
Note
Machinery directive (2006/42/EC)
When the European common market was launched, a decision was made that the domestic
Standards and regulations of all of the EU Member States relating to the technical
implementation of machines would be harmonized. This meant that, as an internal market
Directive, the content of the Machinery Directive had to be implemented by the individual
member states as national legislation. For the Machinery Directive, this was realized with the
aim of achieving standard protective goals and, in turn, removing technical trade barriers. In
accordance with the definition of a machine ("an assembly of linked parts or components, at
least one of which moves"), this Directive is extremely extensive. The revised version from
2006, which shall be binding as of Dec. 29, 2009 without transistional period, has expanded
its area of application and now includes "Logic units to ensure safety functions".
The machinery directive involves the implementation of machines. It has 28 Articles and 12
Annexes. The basic safety and health requirements specified in Annex I of the Directive
must be fulfilled for the safety of machines.
The protective goals must be implemented responsibly to ensure compliance with the
Directive.
Manufacturers of a machine must verify that their machine complies with the basic
requirements. This verification is facilitated by means of harmonized standards.
Five safety rules
When carrying out any kind of work on electrical devices, the following "five safety rules"
must always be observed in accordance with EN 50110-1 and EN 50110-2:
• 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.
