6.1 Installation information

SINAMICS DCM Base Drive panels are designed as chassis units intended to be mounted
inside a protective enclosure or inside a control room. The units are to be mounted
vertically in cubicles usually with the power connections at the top and the control
connections at the bottom. A minimum 100-mm (4-inch) clearance must be kept above and
below the converter in order to ensure unrestricted cooling airflow. The open chassis units
are designed to operate in a 45°C (15 to 125 Amp units) and 40ºC ambient (210 to 2800
Amp units). When enclosed in a cubicle the ambient temperature outside the cubicle should
not exceed 40°C, which then allows for a 5°C-temperature rise inside the cubicle. Care must
be taken in the selection of the cubicle so that the internal temperature rise does not
exceed 5°C. Refer to section 5 for approximate system de-rating data.
Note, Important: This equipment is designed and package-protected to handle the normal
shock and vibration typically encountered in shipment. Do not install these SINAMICS DCM
Base Drive panels on equipment subject to shock or vibration. Select a reasonably
clean location for installation, free from corrosive or conductive materials or fumes.
CAUTION
Failure to lift the SINAMICS DCM Base Drive panel in the correct manner can result in
bodily injury and/or property damage.
The SINAMICS DCM Base Drive panel must be lifted using suitable equipment and under
the instruction of appropriately qualified personnel.
The user is responsible for installing the SINAMICS DCM Base Drive panel, motor,
transformer as well as other equipment according to safety regulations (e.g. NEC),
as well as all other relevant national or local regulations regarding cable sizing and
protection, grounding, disconnects, overcurrent protection, etc.
The SINAMICS DCM Base Drive panels must be installed in accordance with the relevant
safety regulations (e.g. NEC), as well as all other relevant national and local regulations.
It must be ensured that the grounding, cable sizing and appropriate short-circuit
protection have been implemented to guarantee operational safety and reliability.
Note, Important: SINAMICS DCM Base Drive panels have high-speed semiconductor
fuses installed for protection of the thyristors in the event high fault currents are
encountered. These fuses are "special purpose" fuses, and do not meet the requirements
of the NEC for short-circuit protection in motor branch circuits. It is necessary to provide
other devices for short-circuit protection. Typically molded case circuit breakers or
NEC style fuses are used for this purpose. Refer to applicable sections of the NEC for
additional information.
CAUTION
The fundamental principles of EMC in Section 6.1 of SINAMICS DCM Converter operating
instructions (Order # C98130A7066A1047619) must be adhered to
when installing any unit.
