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 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
NOTICE
Sine-wave filter damage due to interchanged connections

• Connect the incoming cable from the Motor Module to 1U1, 1V1, 1W1.
• Connect the outgoing cable to the load at 1U2, 1V2, 1W2.
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.
