3.8 Line reactors
3.8.1

Description

The line reactors limit low-frequency line harmonics and reduce the load on the rectifiers in
the Power Modules. They are used to smooth voltage spikes (line supply faults) or to bridge
voltage dips/interruptions when commutating.
Power Modules PM240-2 FSD and FSE have integrated DC link reactors and therefore do
not need a line reactor.

Safety instructions for line reactors

Danger to life if the fundamental safety instructions and residual risks are not heeded
Failure to heed the fundamental safety instructions and residual risks in Chapter 1 can
result in accidents causing severe injuries or death.
• Follow the fundamental safety instructions.
• Consider the residual risks on the risk assessment.
Danger to life due to electric shock in the event of missing touch protection
Serious injury or death can result when live parts are touched.
• For the line reactors, use touch protection according to IPXXA or corresponding to the
Danger of fire through overheating for insufficient ventilation clearances
Insufficient ventilation clearances can result in overheating with danger to persons as a
result of smoke and fire. Further, increased failures can occur and the service life of
components shortened.
• Ensure 100-mm ventilation clearances above and below the component.
