4.6.3 Adjusting the fan voltage (-G1 -T10, -T1 -T10)
The power supply for the device fans (230 V 1 AC) in the Active Line Module (-G1 -T10) and
in the Motor Module (-T1 -T10) is generated from the main supply system by means of
transformers.
The locations of the transformers are indicated in the layout diagrams supplied.
The transformers are fitted with primary taps so that they can be fine-tuned to the rated
supply 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 (-G1 –T10 and -T20 or -T1 –T10 and -T20) are installed in the following
cabinet units. The two primary terminals on these devices must be set together.
With 380 V – 480 V 3 AC:
6SL3710-7LE36-1AA0, 6SL3710-7LE37-5AA0, 6SL3710-7LE38-4AA0, 6SL3710-7LE41-
0AA0, 6SL3710-7LE41-2AA0, 6SL3710-7LE41-4AA0
With 500 V – 690 V 3 AC:
6SL3710-7LG34-1AA0, 6SL3710-7LG34-7AA0, 6SL3710-7LG35-8AA0, 6SL3710-
7LG37-4AA0, 6SL3710-7LG38-1AA0, 6SL3710-7LG38-8AA0, 6SL3710-7LG41-0AA0,
6SL3710-7LG41-3AA0
Figure 4-3 Setting terminals for the fan transformers (380 V – 480 V 3 AC / 500 V – 690 V 3 AC)
The line voltage assignments for making the appropriate setting on the fan transformer are
indicated in the following tables.
Note
With the 500 V – 690 V 3 AC fan transformer, a jumper is inserted between the "600 V"
terminal and "CON" terminal. The "600V" and "CON" terminals are for internal use.
