Safety instructions for line filters
Danger to life if the fundamental safety instructions and residual risks are not observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Observe the fundamental safety instructions.
• Consider the residual risks for the risk evaluation.
Danger to life due to electric shock in the event of missing touch protection
Death or serious injury can result when live parts are touched.
• For the line filter, use touch protection according to IPXXA or corresponding to the local
installation regulations.
Danger of fire through overheating for insufficient ventilation clearances
Insufficient ventilation clearances result in overheating with danger to persons as a result of
smoke and fire. Further, the line filter can be thermally damaged.
• Maintain 100 mm ventilation clearances above and below the line filter.
Damage due to multiple loads being connected to the same line infeed point
Damage may occur if multiple loads are connected to the same line infeed point.
• Suppress interference on the additional loads using appropriate line filters.
Line filter damage due to interchanged connections
Interchanging the input and output connections will damage the line filters.
• Connect the incoming line supply cable to LINE L1, L2, L3.
• Connect the outgoing cable to the Power Module at LOAD/LAST L1´, L2´, L3´ (U, V, W).
Damage of further loads due to incorrect line filters
Unsuitable line filters can cause line harmonics, which damage or destroy loads connected
to the same line supply.
• Only use line filters released by SIEMENS for SINAMICS.
