Conformance to EC Directives Conformance

1.7.1 Concepts
The concepts for the directives EMC and Low Voltage are as follows:
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
machines. The actual products have been checked for conformity to EMC
standards. 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
Directives will vary depending on the configuration, wiring, and other
conditions of the equipment or control panel in which the OMRON devices
are installed. The customer must, therefore, perform final checks to confirm
that devices and the over-all machine conform to EMC standards.
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC or 75 to
1,500 VDC meet the required safety standards.
1.7.2 Conformance to EC Directives
The Trajexia Motion Controllers comply with EC Directives.
To ensure that the machine or device in which a system is used complies
with EC directives, the system must be installed as follows:
1. The system must be installed within a control panel.
2. Reinforced insulation or double insulation must be used for the DC
power supplies used for the communications and I/O power supplies.
