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.
• Always mount the dv/dt filters compact plus voltage peak limiter in a vertical, upright
Risk of burns due to high surface temperature of the dv/dt filter compact
The surface temperature of the dv/dt filters compact may exceed 80 °C. You can get
seriously burnt when touching the surface.
• Mount the dv/dt filters compact so that they cannot be touched. If this is not possible,
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 on devices with the article numbers 6SL3000-2DE41-4EA0, 6SL3000-2DG38-
1EA0, and 6SL3000-2DG41-3EA0.
• 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.
