  • Safety Guidelines This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are graded according to the degree of danger.

    DANGER indicates that death or severe personal injury will result if proper precautions are not taken.

    WARNING indicates that death or severe personal injury may result if proper precautions are not taken.

    CAUTION with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.

    CAUTION without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.

    NOTICE indicates that an unintended result or situation can occur if the corresponding information is not taken into account.

    If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage.

    Qualified Personnel The device/system may only be set up and used in conjunction with this documentation. Commissioning and operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes in this documentation qualified persons are defined as persons who are authorized to commission, ground and label devices, systems and circuits in accordance with established safety practices and standards.

    Prescribed Usage Note the following:

    WARNING This device may only be used for the applications described in the catalog or the technical description and only in connection with devices or components from other manufacturers which have been approved or recommended by Siemens. Correct, reliable operation of the product requires proper transport, storage, positioning and assembly as well as careful operation and maintenance.

    Preface This documentation contains instructions on and examples of the arrangement of control and drive components in the control cabinet and their cooling (heat dissipation) using the example of the SINAMICS S120 booksize and SIMODRIVE 611 device types, including the SIMOTION and SINUMERIK drive-related controllers, referred to in the following as "device combination", and instructions on setting up in compliance with EMC requirements. Most of the instructions relate to device combinations with "internal cooling", where all of the heat loss occurs inside the cabinet. Particular reference is made in some chapters to different types of cooling such as "external cooling", "water cooling" or "cold plate". Part of the content of this documentation was devised in a working group with the following companies: Audi AG DaimlerChrysler AG EPLAN Software & Service GmbH & Co. KG Felsomat GmbH & Co. KG NILES - SIMMONS Industrieanlagen GmbH Rittal GmbH & Co. KG Siemens AG Many instructions and examples can be applied to other device types by analogy. If you do not follow these instructions and/or the instructions in the device-specific technical user documentation, this can lead to malfunctions and significantly reduce the service life of the equipment, and result in premature component failure.

    An approximate description of the thermal correlations can be provided by the Arrhenius equation: ● A temperature rise of approx. 10 K causes a halving of service life ● A temperature rise of approx. 10 K causes a doubling of the failure rate

    Examples from practical experience The following examples illustrate how markedly the temperatures rise if the installation guidelines are not observed. The effect on failure rates and service life is determined with the aid of the chart, "Service life and failure rate according to the Arrhenius equation". Example 1: Cable duct spacing on SIMODRIVE 611 In operation under reference conditions, temperatures in the interior of the device are established in accordance with the left-hand illustration in operation with a defined load given correct installation with 100 mm spacing for the cable ducts. If under identical conditions the spacing of the cable ducts is reduced to approximately 40 mm as shown in configuration A, the temperatures rise by about 10 K. The failure rate rises to roughly double the usual figure as a result. Service life is shortened to approximately 50 %. If under identical conditions the spacing of the cable ducts is reduced to approximately 15 mm as shown in configuration B, the temperatures rise by about 16 K. The failure rate rises to roughly three times the usual figure as a result. Service life is shortened to approximately 30 %.

    Example 2: Cables on the ventilation grille of 50 mm-wide SIMODRIVE 611 modules In operation under reference conditions, temperatures in the interior of the device are established in accordance with the left-hand illustration in operation with a defined load given correct installation without cables on the ventilation grille. If under identical conditions a cable is laid on the ventilation grille, the temperatures rise by about 10 K. The failure rate rises to roughly double the usual figure as a result. Service life is shortened to approximately 50 %. If under identical conditions two cables are laid on the ventilation grille, the temperatures rise by about 20 K. The failure rate rises to roughly four times the usual figure as a result. Service life is shortened to approximately 25 %.

    On wider modules the effect of laying cables on the ventilation grille is reduced.
