Adjusting the fan voltage (-T1-T10)

The power supply for the device fan (230 V 1 AC) in the Power Module (-T1- T10) is taken
from the main supply system using a transformer.
The location of the transformer is indicated in the layout diagrams supplied.
The transformer is fitted with primary taps so that it can be fine-tuned to the line voltage.
If necessary, the connection fitted in the factory, shown with a dashed line, must be
reconnected to the actual line voltage.
Note
Two transformers (-T1, -T10, and -T20) are installed in the following cabinet units. The two
primary terminals on these devices must be set together.
• For 3 AC 380 to 480 V: 6SL3710-1GE41-0_Ax
• For 3 AC 500 to 600 V: 6SL3710-1GF37-4_Ax, 6SL3710-1GF38-1_Ax
• For 3 AC 660 to 690 V: 6SL3710-1GH37-4_Ax, 6SL3710-1GH38-1_Ax
Note
For units that are connected in parallel, the setting terminals must be set jointly in both sub-
cabinets:
• For 3 AC 380 to 480 V:
• For 3 AC 500 to 600 V:
• For 3 AC 660 to 690 V:
Figure 4-5
The line voltage assignments for making the appropriate setting on the fan transformer are
indicated in the following tables.
Note
With the 3 AC 660 to 690 V fan transformer, a jumper is inserted between the "600 V"
terminal and "CON" terminal. The "600V" and "CON" terminals are for internal use.
