Danger of fire through overheating for insufficient ventilation clearances
Insufficient ventilation clearances can result in overheating with danger to persons as a
result of smoke and fire. Further, increased failures can occur and the service life of
units/systems shortened.
• It is essential that you maintain 100 mm ventilation clearances above and below the
Risk of burns resulting from high surface temperature of the motor reactor
The motor reactors can become very hot. You can be severely burnt when touching the
surface.
• Mount the motor reactors so that they cannot be touched. If this is not possible, at the
NOTICE
Damage to the motor reactors 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. There is a risk that the motor reactor will be thermally
damaged.
• Only use motor reactors that SIEMENS has released for SINAMICS.
NOTICE
Risk of damaging motor reactors by exceeding the maximum output frequency
The maximum permissible output frequency when motor reactors are used is 150 Hz. The
motor reactors can be damaged if the output frequency is exceeded.
• Do not operate the motor reactors above the maximum permissible output frequency of
NOTICE
Damage if the maximum pulse frequency is exceeded
The maximum permissible pulse frequency when motor reactors are used is 4 kHz. The
motor reactors can be damaged if the pulse frequency is exceeded.
• Do not operate the motor reactors at the Power Module above the maximum permissible
