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.
