Fig. 4-1 Setting terminals for the fan transformer (380 V – 480 V / 660 V – 690 V)
The supply voltage assignments for making the appropriate setting on the fan
transformer are indicated in the following table.
NOTE
With the 660 V – 690 V fan transformer, a jumper is inserted between terminal
“600 V” and terminal “CON”. Terminal “CON” is for internal use.
IMPORTANT
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.
