Highlights
● Ready for connection and ready for switching on
The SINAMICS DC MASTER Cabinet is ready for connection and ready for switching on.
This can reduce planning and commissioning times and plant downtimes, and
functionality is guaranteed by means of optimally coordinated components.
● Supply for motor fan
The power supply for the external fan of the DC motor is part of the basic version,
including motor circuit breakers. The set values of the circuit breaker can be tuned to the
motor by selecting the corresponding option.
● Flexibility in the auxiliary power supply
SINAMICS DC MASTER Cabinets can be used universally and flexibly for wide voltage
ranges. Adaptation to the existing control voltage is particularly significant for
modernization of existing installations. The auxiliary power supply of the converter
cabinet is adjusted by specifying the existing mains voltage. If no separate auxiliary
power supply is available, it is branched off inside the cabinet.
● EMC zone concept
Thanks to the EMC zone concept, the SINAMICS DC MASTER Cabinet is ideally
designed for industry both in terms of robustness to interference and in terms of low
emitted interference.
The zone concept applies to the spatial arrangement of the built-in components. These
include the electrical/electronic devices, but also cables for energy and signals, which
may be sources of interference or susceptible equipment. Separate cable routing and
high frequency low-ohm connections are a characteristic of the concept. In order to apply
this concept to the line-side as well, the easily accessible customer interfaces not only
provide the appropriate terminals and shield buses, but also provide sufficient space to
place cable shields as per regulations.
The drive cabinet designed as per this concept provides fault-free operation in terms of
electromagnetic compatibility.

● Monitoring the internal temperature of the drive cabinet
The availability of a drive is in practice often influenced by changes in environmental
conditions:
– Additional external heat sources in the environment can increase the air intake
– Unusually high contamination in the air clogs up the air intake filter.
– Subsequent addition to the drive cabinet of devices with high heat loss places an
Monitoring the internal temperature of the drive cabinet via a PTC thermistor sensor can
identify these influences early and remedial measures can be applied in good time.
