LCL Filter Fan DC Power Supply (SK-Y1-DCPS2-F13) Removal and Installation
This kit contains the following components.
• Fan DC power supply circuit board
• New X51 cable (fan circuit board to AFE power structure connections)
• New X52 cable (fan motor thermal switch to AFE power structure
connections)
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 fan DC power supply circuit board.
The LCL filter fan DC power supply wiring diagram is shown in Figure 34 . The
diagram shows the connections to the AFE power structure and DC bus.
