Notes

8.1.1

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

Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account remaining risks.
Danger of injury caused by foreign objects in the device
Parts (e.g.: drilling chips, end sleeves) falling into the device can cause short-circuits and
damage 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
