Maintenance

Not observing fundamental safety instructions and residual risks
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.
The SINAMICS DCM Control Module must be provided with extensive protection measures
against contamination in order to prevent voltage flashovers and, therefore, destruction. Dust
and foreign bodies must be thoroughly removed at given intervals depending on the level of
soiling and certainly at least once every 12 months. The unit must be blown out with dry
compressed air at a maximum of 1 bar, or cleaned using a vacuum cleaner.
The screw connections (also the protective conductor connections) must be retightened
each time that the SINAMICS DCM Control Modules are maintained.
