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.
