Conformance to EC Directives 6
• When transporting the Unit, use special packing boxes and protect it from
being exposed to excessive vibration or impacts during transportation.
• CPU Bus Units will be restarted when routing tables are transferred from
a Programming Device to the CPU Unit. Restarting these Units is required
to read and enable the new routing tables. Confirm that the system will
not be adversely affected before allowing the CPU Bus Units to be reset.
• When the settings (IP address or tag data link settings) of the EtherNet/IP
Unit or built-in EtherNet/IP port are transferred from a Programming
Device, all of the destination EtherNet/IP Units or built-in EtherNet/IP
ports (nodes) will be reset in order to enable the transferred settings.
Transfer settings to the EtherNet/IP Units or built-in EtherNet/IP ports only
after verifying that restarting the Units will not cause any problems in the
system.
• If a repeater hub is used for EtherNet/IP tag data links (cyclic communica-
tions), the network's communications load will increase, data collisions
will occur frequently, and stable communications will be impossible.
Always use a switching hub when using tag data links in the network.
• Before resetting a CPU Bus Unit or Special I/O Unit, always verify that
restart the Unit will not cause any problems in the system.

6-2 Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or the
overall machine. The actual products have been checked for conformity to
EMC standards (see the following note). Whether the products conform to the
standards in the system used by the customer, however, must be checked by
the customer.
EMC-related performance of the OMRON devices that comply with EC Direc-
tives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices
and the overall machine conform to EMC standards.
Note Applicable EMS (Electromagnetic Susceptibility) and EMI (Electromagnetic
Interference) Standards in the EMC (Electromagnetic Compatibility) stan-
dards are as follows:
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).
