Exchanging the Main Power Supply
The main power supply (MPS) (part number 0950-2528) is located below the
SPM board in the rear part of the spectrophotometer.
The main power supply (MPS) is in a separate housing. It does not contain
any servicable parts inside. In case it is defective, it must not be opened but
has to be exchanged as a complete assembly.

plastic and sheet metal front and rear covers off, see “Removing and Replacing
