4.9.3 Feeder for external auxiliaries / motor blower (option L17)
Description
This option includes a switched outgoing feeder with 3-phase AC line voltage and max. 10 A
fuse protection for an external auxiliary device /motor fan. The voltage is tapped at the
converter input upstream of the main contactor/circuit breaker and, therefore, has the same
level as the supply voltage. The outgoing circuit can be switched within the drive or
externally.
