Rel.: 2.0 - September 2004      -      Page 5

3.1- Electrical insulation of the inputs

The inputs may be electrically insulated from the DISP2
circuit; to do this, move the internal jumper a shown in
the first case of the figure on the right side, and connect
the 0 volt terminal of the external supply source to the
terminal «INS» of DISP2. If the electrical insulation is
not needed, use terminal «COM» to supply the external
contacts connected to the inputs, and move the jumper
as shown in the second case of the figure.
The factory setting of this jumper is for NO electrical
insulation.
