Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.
This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.
The manual was properly scanned and perfectly readable. The only small problem is that I couldn't use my dear Ctrl + F to find a word I needed.

CORD CLAMP
The wire coloured green and yellow must be connected to the terminal marked with the letter «E» or by the earth symbol or coloured green and yellow. The wire coloured blue must be connected to the terminal «N» or coloured black. The wire coloured brown must be connected to the terminal marked «L» or coloured red. Upon completion there must be no cut, or stray strands of wire present and the cord clamp must be secure over the outer sheath. WARNING: A cut off plug inserted into a 13 amp socket is a serious safety (shock) hazard. Ensure that the cut off plug is disposed of safely.
The power supply cable must be accessible after installing the machine.
Permanent connection
In the case of permanent connection it is necessary that you install a double pole switch between the appliance and the electricity supply (mains), with a minimum gap of 3mm between the switch contacts and of a type suitable for the required load in compliance with the current electrical regulations. The switch must not break the yellow and green earth cable at any point.
