Fire hazard due to overheating because of inadequate ventilation clearances
Inadequate ventilation clearances can cause components to overheat. This can result in
severe injury or death due to fire and smoke. This can also result in increased failure rates
and a shorter service life for Line Modules.
• Maintain the 80 mm clearances above and below the Line Modules.
Fire hazard due to overheating when the required cable cross-sections of power cables is
fallen below
Power cables with excessively low cross-sections can cause them to overheat. This can
result in severe injury or death due to fire and smoke.
• Only use power cables with sufficiently large cross-sections. Take into account the
Fire hazard due to overheating when the total length of the power cables is exceeded
Overheating can result when the total length of the power cables is exceeded. This can
result in severe injury or death due to fire and smoke.
• Ensure that the total length of the power cables (motor supply cables and DC link
Note
Operation on line supplies where energy recovery is not possible
In line supply systems without energy recovery capability (e.g. a diesel generator), device
faults can occur as the braking energy cannot be dissipated.
• For line supplies without regenerative feedback capability (e.g. diesel generator),
deactivate the regenerative feedback capability of the Line Modules using the appropriate
parameter (see SINAMICS S120/S150 List Manual).
• The braking energy must then be dissipated via an additional Braking Module with
braking resistor in the drive line-up.
