Figure 4-12 Connecting terminals for the fan transformers (500 to 690 V 2 ph. AC)
The line voltage assignments for making the appropriate setting on the fan transformer are
indicated in the following tables.
Risk of fire due to overheating when device fan voltage is insufficient
If the terminals are not reconnected to the actual line voltage, this can lead to overheating
with a risk of personal injury due to smoke generation and fire.
This can also cause the fan fuses to blow due to overload.
• Set the terminals in accordance with the actual line voltage.
Note
For the fan transformer (500 to 690 V 2 ph. AC), a jumper is inserted between terminal
"600
V" and "CON" terminal - ① in the diagram above). Terminal "CON" is for internal use.
The order numbers for fan fuses that have blown can be found in the spare parts list.
