Removing a PSU
To remove a PSU proceed as follows:
Apply sideways pressure on the PSU handle towards the right and remove the
PSU by pulling it forward
Take care when removing the lower PSU not to damage the panel ribbon cable
Caution:
The power supply does not contain any serviceable parts.
Note:
Check that the two/one switch behind the control panel is set correctly for the number of
PSUs installed to prevent redundant PSU warnings.
Inserting a PSU
To insert a PSU proceed as follows:
Check that any second power supply is the same type as already fitted
Offer up the PSU to the frame guide rails – it may help to turn the lower PSU
handle fully outwards to clear the panel hinge
Carefully push the PSU all the way into its socket
Notes:
Check that the two/one switch behind the control panel is set correctly for the number of
PSUs installed to prevent redundant PSU warnings.
Fitting the fan assembly
To replace the PSU fan assembly proceed as follows:
Offer up the fan assembly ensuring that the two lugs fit into two slots in the right
hand side of the frame
Take care not to damage the panel ribbon cable
Tighten the captive screw to the left of the PSU fan
Connect to the plug on the front panel PCB
If the unit was unpowered it may now be powered and tested
Replacing the PSU fan
It is recommended that PSU fan replacement should be performed as quickly as possible
if performed whilst the frame is powered, to prevent overheating.
Tip:
Close the front panel once the PSU fan assembly is removed when the frame is powered
to allow the front panel fan to operate and provide cooling.
To replace the fan proceed as follows:
If possible disconnect the power cord(s) connected to the frame
Remove the PSU fan assembly as shown in the preceding section
Remove the finger guard and fan by unscrewing the four retaining screws
Replace the fan with a Crystal Vision supplied replacement part to ensure
adequate cooling and continued fire protection
