Main Duct Fan Supply Voltage Selection (Frames 9 & 10)
When wiring up the drive, the customer must check that the Main Duct Fan supply voltage has been setup
for the correct AC Line voltage. This is done by checking the ‘Jumper’ link positions on the Fan Voltage
Selection PCB:
By default, the fan supply jumper links are fitted in the “380V Jumper” positions as shown in the image
above.
For 480V line supplies, the links should be moved from CN2 & CN3, to the “480V Jumper” positions CN4 &
CN5 as shown below:
1. Unscrew the 4x upper
panel fixings.
2. Slide the upper panel up to expose and
access the Fan Supply Voltage Selection
PCB ‘Jumper’ links.
Note: The MMI mounted on the upper panel
is plugged into the control board, so be
careful when handling the upper panel.
