4.9.2 Connection for External Auxiliary Equipment (Option L19)
Description
This option includes a connection fused at max. 10 A for external auxiliary
equipment (for example, separately driven fan for motor). The voltage is tapped at
the converter input and, therefore, has the same level as the supply voltage. The
connection can be controlled internally or externally.

Circuit Proposal for Controlling the Auxiliary Contactor from Within the
Converter
The following circuit, for example, can be used if the auxiliary contactor is to be
controlled from within the converter. The “Operation” message is then no longer
available for other purposes.
