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 more downtimes and
reduced service lives of Line Modules.
• Maintain the 80 mm clearances above and below the Line Modules.
• For the 80 kW and 120 kW Active Line Modules, in addition to the specified minimum
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 all power cables (motor supply cables and DC link cables)
