When
mounting the PC in a control
panel, mount the Racks to an intermediate
plate.
Holes for mounting the Racks to the intermediate plate should
be drilled at
intervals shown in the following diagram. Completely ground the intermediate
mounting plates. Use conductor-plated plates to improve noise immunity.

If
power cables carrying more than 10 A at 400 V or 20 A at 220 V must be run
parallel to I/O wiring,
leave at least 300 mm between the power cables and the
I/O wiring, as shown in the following diagram.
