which must have the corresponding optional modules installed in the instrument.
Open the Indicator as shown in section 4.1 in order to access the connectors in the
Power Supply Board, and one connector in the CPU Board (see figure 21).
The connectors in the Power Supply Board corresponding to outputs 1 and 2

module is placed in the CPU Board and has no label. Any optional module must be
always installed with the component side in the direction of the Display Board, as
