Setting The Voltage Range Of The Auxiliary Voltage Transformers (Option +G344); [T21/T101] Connections (400 - ABB ACS880-207 Hardware Manual

52 Electrical installation
Setting the voltage range of the auxiliary voltage
transformers (option +G344)
The auxiliary voltage transformer ([T21, T101, T111], option +G344) connections are made
at the factory according to the supply voltage and desired output voltage and you do not
need to change the settings during the installation. If needed, check the connections using
the diagrams below.
Transformer [T21] is a standard equipment. Transformers [T101] and [T111] are present if
required by the options specified by the customer.
The voltage settings of transformers [T21] and [T101] are made at terminal blocks
[T21_X1/X2] and [T101_X1/X2] respectively. The settings of transformer [T111] are made
on the transformer itself. The locations of the transformers and the terminal blocks are
shown in section Layout drawing of an auxiliary control cubicle
diagrams delivered with the drive.
