The Mains PSU may be removed once the following have been carried out:
The Mains to the ST700 Rack Assembly has been isolated at the master switch
The 64-way Phase Control ribbon cable has been disconnected from the CPU
The hinged front plate has been opened.
Remove the cables and connectors connected to the PSU, then release the nylon
mounting pillar clips that attach the PSU to the heatsink cover of the Phase Drive
PCB. The clips are retained on the heatsink cover by means of an integral clipping
mechanism on the other end.
When the PSU is replaced, ensure that the clipping mechanism of the mounting pillar
is fully engaged and all the cables and connectors are securely fitted.
Re-assemble the Rack Assembly.
