Figure F.1 I/O Expansion Board Mounting Location
I/O Expansion Board Wiring
Table F.A Recommended Signal Wire Size
A 75 x 2.5 x 0.4 mm (3.0 x 0.1 x 0.02 in.) flathead screwdriver is
recommended for connecting wire to the terminal block inputs. Strip the
ends of the cables to a length of 6.5 mm (0.26 in.).
Important: To improve the noise immunity it is recommended that you
connect the common of the outputs (terminals 2, 4, 5 and 15 of
the I/O Expansion board) with the ground (terminal 10 or 20)
on the standard I/O terminal blocks on the Control board. If this
is not possible, these terminals must be grounded by means of a
0.1
μ
f/250V capacitor.

The Analog and Digital I/O Expansion circuit board is not factory installed.
