Connection for external auxiliary equipment (option L19)
Description
This option includes an outgoing circuit fused at max. 10 A for external auxiliary equipment
(e.g. separately-driven fan for motor). 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 converter or externally.

Circuit proposal for controlling the auxiliary contactor from within the converter
Circuit proposal as standard
A free digital output of the Control Unit can be used to control the auxiliary contactor; it uses
a line-side relay to control auxiliary contactor -K155.
Signal r0899.11 (pulses enabled) must also be interconnected to the selected digital output
of the Control Unit.
