Safety information

Danger to life if the fundamental safety instructions and remaining risks are not carefully
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.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Fire hazard 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 clearances above and below the components.
Risk of burns due to high surface temperature of the dv/dt reactor
The surface temperature of the dv/dt reactors may exceed 80 °C. You can get seriously
burnt when touching the surface.
• Mount the dv/dt reactor so that it cannot be touched. If this is not possible, attach a
NOTICE
Damage to the voltage peak limiter due to interchanged connections
The voltage peak limiter will be damaged if the input and output connections are
interchanged.
• Connect the incoming cable from the DC link of the Motor Module to DCPS, DCNS.
• Connect the outgoing cable to the dv/dt reactor to 1U2, 1V2, 1W2.
NOTICE
Damage to the dv/dt filter 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.
• Only use dv/dt filters that SIEMENS has approved for operation with SINAMICS.
