Notes
5.1.1
General
The modular concept of SINAMICS S120 chassis units allows a wide range of potential device
combinations. For this reason, it is impossible to describe each individual combination. This
section instead aims to provide some basic information and general rules on the basis of
which special device combinations can be configured to ensure electromagnetic compatibility
and adequate cooling – therefore ensuring reliable operation with the appropriate
functionality.
SINAMICS S120 components are designed for installation in the appropriate enclosures,
which can take the form of cabinet units or control boxes made of steel that provide
protection against shock and other environmental effects. They are also part of the EMC
concept.

Safety information
WARNING
Not observing fundamental safety instructions and residual risks
Not observing fundamental safety instructions and residual risks listed in Chapter 1 can
result in accidents with severe injuries or death.
•
Comply with the fundamental safety instructions.
•
When assessing the risk, take into account remaining risks.
WARNING
Injuring caused by foreign objects in the device
Parts and components falling into the device (e.g. drilling chips, end sleeves, etc.) can cause
short-circuits and damage to the insulation. This can lead to serious injuries (arcing, bangs,
pieces flying out of the equipment).
•
Only perform installation and other work when the devices are current-free.
•
Cover the ventilation slits during the installation of the cabinet and remove the cover
before switching on.
