16. ACx 604/607 units (except frame R7 units) include a transformer
(T41) which supplies power to the cooling fan at base of the

the factory. Adjust the setting if it does not correspond to the
supply voltage. To access the transformer remove the front cover
of the converter unit with the ABB logo. After adjusting the voltage
put the plate back into its place.
17. Cabinets with the line contactor option include an internal auxiliary
voltage transformer. Its input voltage is set to 415 V, 500 V or
690 V at the factory. Adjust the setting if it does not correspond to
the supply voltage. The transformer is located in the upper right
part of the cabinet, and is visible when the cabinet door is opened.
