General

Description
The sine-wave filter limits the voltage gradient and the capacitive charge/discharge currents
which usually occur with inverter operation. It also prevents additional noise caused by the
pulse frequency. The service life of the motor is as long as that attained with direct mains
operation.
Non-observance of the 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 residual risks.
Fire through overheating due to insufficient 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 sine-wave filter
The surface temperature of the sine-wave filters can exceed 80 °C. You can get seriously
burnt when touching the surface.
• Mount the sine-wave filter so that it cannot be touched. If this is not possible, attach a
Sinusoidal filter
