Fire hazard due to overheating because of inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel due to
smoke and fire. This can also result in increased failure rates and a shorter service life of
the components.
• Maintain the 100 mm clearances above and below the components.
Risk of burns due to high surface temperatures
The motor reactors can become very hot. You can get seriously burnt when touching the
surface.
• Mount the motor reactors so that contact is not possible. If this is not possible, attach
• To prevent adjacent components from suffering damage due to these high
