Safety instructions for motor reactors

Danger to life if the fundamental safety instructions and residual risks are not heeded
Failure to heed the fundamental safety instructions and residual risks in Chapter 1 can
result in accidents causing severe injuries or death.
• Follow the fundamental safety instructions.
• Consider the residual risks on the risk assessment.
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. This can also result in increased downtime and reduced service
lives for devices/systems.
• 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 due to use of non-approved components
If components are used that have not been approved, damage or malfunctions can occur in
the devices or the system itself. There is a risk that the motor reactor will be thermally
damaged.
• Use only motor reactors that have been approved for SINAMICS by Siemens.
NOTICE
Damage to the motor reactor if the maximum output frequency is exceeded
The maximum permissible output frequency when motor reactors are used is 150 Hz. At a
higher output frequency, the motor reactor may be damaged.
• Do not operate the motor reactors above the maximum permissible output frequency of
