LCL Filter DC Fan Power Supply (SK-Y1-DCPS1-D1K3 or SK-Y1-DCPS1-E1K0) Removal and
Installation
Note: It is not necessary to remove the fan assembly from the LCL filter, but by
doing so, it may be easier to replace the DC fan power supply circuit board.
The LCL filter DC fan power supply wiring diagram is shown in Figure 33 . The
diagram shows the connections to the AFE power structure and DC bus.

IMPORTANT Before doing any work, disconnect the AFE power structure from the AC supply,
and wait until the fan stops and the indicators on the keypad turn off. (If a
keypad is not attached, see the indicator through the keypad base.) Wait 5
more minutes before doing any work on the DC-to-DC power supply. Do not
even open the cover until after this time has expired.
