Selecting/Verifying Fan Voltage 1336 IMPACT drives, 45 kW (60 hp) to 448 kW (600 hp) that have
cooling fans use a transformer to match the input line voltage to the
proper fan voltage. If you are using an input voltage other than the
standard 240, 480, or 600V AC, you may need to change the
transformer tap.
To change a transformer tap, follow these instructions:
1. Ensure that all power has been removed to the drive.
2. Locate the transformer in the lower left corner of the drive
chassis. Note lead placement (tap being used).
3. Determine the correct tap from Figure 4.7 and verify.
4. If the present tap is incorrect, remove the insulating sleeve from
the correct tap.
5. Remove the wire lead presently connected.
6. Place the wire lead on the selected tap.
7. Replace the insulating sleeve on the unused tap.
