Safety information

Not observing fundamental safety instructions and residual risks
Not observing fundamental safety instructions and residual risks listed in Chapter 1 can
result in accidents with severe injuries or death.
• Comply with the fundamental safety instructions.
• When assessing the risk, take into account remaining risks.
Fire due to overheating because of inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel through
smoke development and fire. Furthermore, an increased number of failures and shorter
service life of the components can occur.
• Maintain 100 mm ventilation clearances above and to the side of the component.
Burns resulting from high surface temperature of the motor reactor
The surface temperature of the motor reactors can exceed 80 °C. You can get seriously
burnt when touching the surface.
• Mount the motor reactor so that it cannot be touched. If this is not possible, attach a
NOTICE
Damage to the Motor Module by using components that have not been released
When using components that have not been released, damage or malfunctions can occur at
the devices or the system itself.
• Only use motor reactors that SIEMENS has released for SINAMICS.
NOTICE
Risk of damaging the motor reactor by exceeding the maximum output frequency
The maximum permissible output frequency when a motor reactor is used is 150 Hz. The
motor reactor can be damaged if the output frequency is exceeded.
• Operate the motor reactor with a maximum output frequency of 150 Hz.
