Figure 4-4
Setting terminals for the fan transformers (500 V – 600 V 3 AC)
The supply voltage assignments for making the appropriate setting on the fan transformer
are indicated in the following tables.
Note
With the 660 V – 690 V 3 AC or 500 V – 600 V 3 AC fan transformer, a jumper is inserted
between terminal "600 V" and terminal "CON". The "600V" and "CON" terminals are for
internal use.
NOTICE
If the terminals are not reconnected to the actual supply voltage:
•
The required cooling capacity cannot be provided because the fan rotates too slowly;
•
The fan fuses may blow due to an overcurrent.
Note
The order numbers for fan fuses that have blown can be found in the spare parts list.
