Checking the settings of the cooling fan transformer
Check the tap settings of all cooling fan transformers. Cooling fan transformers T115
and T125 are present depending on drive configuration. If the delivery contains an
incoming unit, the cooling fan transformer connections are made at the factory. The
connection of the primary winding of the fan transformer depends on the actual
system voltage.
The voltage settings of cooling fan transformers T115 and T125 are made at terminal
blocks T115_X1/X2 and T125_X1/X2 respectively.

Connecting the power supply cable for the charging circuit
If the delivery contains an incoming cubicle (ie, the drive is equipped with a main circuit
breaker ([Q1], option +F255), or main contactor ([Q2], option +F250), the charging
circuit connections are made at the factory. The charging circuit components are
located in the incoming cubicle. If the delivery does not contain incoming cubicle, see
the delivery-specific circuit diagrams for wiring.
Activate and tune the charging function in the control program. For information on
tuning the parameters, see
