9.2.5.8—Unshielded Discrete I/O
I/O Module in Cabinet

Use Shielded cable from MicroNet module to I/O module (FTM, etc.)

Ground cable direct at MicroNet module and I/O module

Locate as close to I/O cable entry point as possible;

Locate I/O module away from sensitive analog areas (> 6”);
I/O Cable w/ I/O Module in Cabinet

Route I/O cable against cabinet metal wall from entry point to I/O module;

Do not let other cables within 12” of unshielded discrete I/O cables if they
are parallel for > 2’

Do not let other cables within 6” of unshielded discrete I/O cables if they are
parallel for less than 2’

Limit length of unshielded I/O cable inside the cabinet. Any length over 2’ is
too long

If lengths greater than 2’ are required, special considerations should be
used to separate this unshielded wiring from other circuits and minimize
electromagnetic and RF emissions.
I/O Module not in Cabinet

Route cable from MicroNet module to I/O module with cable against cabinet
metal wall

Ground “MicroNet module to I/O module” cable at entry point to cabinet and
to I/O module
9.2.6—Third Party Hardware
CE Compliant to Light Industrial Levels

Locate inside the cabinet, away from all I/O cables that enter or exit the
cabinet by >12”

Locate from all other cables > 6” away

Use only CE compliant devices
CE Complaint to Industrial Levels

Locate based on Zoning restrictions
9.2.7—Ethernet I/O Connections

Use Shielded Twisted Pair (STP) category 5 Ethernet cable

Route Ethernet cable away from all other Internal cabling and external I/O
cabling

Ground internal Ethernet cable at the CPU card and at the entry point to the
cabinet
9.2.8—CAN I/O Connections

A shielded CAN cable as defined in section 5.1.9 of volume 1 of this
manual.

Route the CAN cable away from all other Internal cabling and external I/O
cabling.

Ground the internal CAN cable shield at the entry point to the cabinet.

AC couple the CAN cable shield to earth at each of the CAN devices
external to the MicroNet cabinet.

AC couple the CAN cable shield to earth at each of the CAN devices
internal to the MicroNet cabinet.
