(1) Important: SCR Bus Supplies are designed to be field maintained only. Normal maintenance components (fan, fuses, fuse
monitor switch, printed circuit boards (precharge, gate, and snubber), and precharge relay are available. Additional catalog
numbers are provided for troubleshooting and technical support information only.
(2)
Extensive disassembly is required to replace the fan assembly. Please consider using Rockwell Automation Remanufacturing
Services.
(3) When replacing these fuses, always properly position them so that their fuse trip indicators (plungers) point toward the fuse trip
detection board.
