, including removal and installation of the following items:
• AC fan inverters
• AC fan capacitors
• AC main cooling fans
• DC fan power supplies
• DC main cooling fans
• Fan fusing
ATTENTION:
The sheet metal cover and mounting screws on the ASIC circuit
board that is on the power structure are energized at (-) DC bus potential high
voltage. Risk of electrical shock, injury, or death exists if someone comes into
contact with the assembly. Verify that the -DC bus wire is properly connected
to the ASIC chassis cover.
