LCL Filter DC Fan Power Supply Kit (SK-Y1-DCPS2-F10) 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
. 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.
