Derating data

2.11.1

Derating data for booksize format

SINAMICS S120 Cabinet Modules with power units, booksize format, and the associated
system components are dimensioned for an ambient temperature of 40 °C and installation
altitudes up to 1000 m above sea level. If SINAMICS S120 Cabinet Modules with power
units in the booksize format are operated at ambient temperatures higher than 40 °C and/or
installation altitudes higher than 1000 m above sea level, then the corresponding derating
factors must be taken into account as a function of the ambient temperature and/or the
installation altitude. These derating factors differ from the derating factors for chassis format
power units and are specified in Catalog PM21 / SINAMICS S120 Drive System. They are
valid for SINAMICS S120 Cabinet Modules with booksize format power units in degrees of
protection IP20, IP21, IP23, IP43 and IP54.

General

SINAMICS S120 Cabinet Modules as well as the associated system components are
dimensioned for an ambient temperature of 40 °C and installation altitudes up to 2000 m
above sea level.
S120 Cabinet Modules include Basic Line Modules, Smart Line Modules, Active Line
Modules and Motor Modules with power units, chassis format including the associated
system components, (e.g. line filter, chassis Braking Modules and motor filter), as well as
Line Connection Modules and Auxiliary Power Supply Modules.
Exceptions are S120 Cabinet Modules with power units, Booksize format and the Central
Braking Modules. This derating data can be taken from Chapter "Cabinet Modules" in
subchapter "Derating data" of the particular S120 Cabinet Modules.
