2. Referring to the diagram below, use a 3mm flat-bladed screwdriver to loosen the screw
terminals for the incoming power wiring terminals on the left of the terminal aperture
and withdraw the wires from the terminals. Then loosen the nut on the protective
earthing(P.E.)/grounding stud and remove the ring terminal.
3. Next, identify the terminals on the right that accept the wiring for the display module
and the COM module. Using the 3mm flat-bladed screwdriver insert the blade into the
slot above the wire entry points for each terminal, in turn, to allow the wire to be
withdrawn. Repeat this procedure until all eight wires have been disconnected.
4. When all internal wiring has been disconnected, loosen the cable gland securing nut for
each of the three cables entering the PSU – i.e. Power, Display and Comms - and
withdraw each of the cables from the PSU housing.
5. Finally, loosen and remove the four mounting nuts (positions ‘A’) securing the body of
the PSU module to the display module and lift away the PSU module from the display.
6. Temporarily replace the terminal cover plate on the PSU and attach it with the four
screws (‘B’) removed previously and set the module aside, with its four fixing nuts and
washers, in a safe place for re-installation later.
