Electrical installation
4.7 Power connections
The line voltage assignments for making the appropriate setting on the fan transformer are
indicated in the following tables.
Note
Fan transformer for 660 to 690 V 3 AC
With the 500 V to 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.
Danger of fire due to overheating resulting from insufficient device fan voltage
If the terminals are not reconnected to correspond with the actual line voltage, overheating
and risks to personnel due to smoke and fire may result.
This can also cause the fan fuses to rupture due to overload.
• Set the terminals in accordance with the actual line voltage.
Note
Article numbers for fan fuses
The article numbers for fan fuses that have blown can be found in the spare parts list.
