F.1 Precautions for Installation
Grounding
The grounding wire for a connector unit must be as short as possible (less than 5 cm)
and be connected to the metal part of the chassis.
I/O Cable Shielding
The digital I/O cables must be bundled and shielded with the mesh shielding jacket
(made by Kitagawa Industries, Ltd., of part No. CB-ME-40, for example) as a whole.
The analog I/O cables must also be shielded in a similar way.
These shielded cable bundles must be connected to the metal part of the cabinet with a
short grounding strap (less than 10 cm).
Shielded Cabinet
Shielded cabinets must be used for the Integrated Controllers and I/O subsystems. One
shielded cabinet model is available from VERO Electronics.
The Integrated Controllers and I/O subsystems installed in the shielded cabinet (made by
VERO Electronics, of part No. IMRAK3400, for example) have already been tested for
conformity with the EMC Specifications.
