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 ma-chines. 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 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.
Note
Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility):
EMI (Electromagnetic Interference):
EN61000-6-2, EN50082-2
EN55011 Class A Group 1
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.

Conformance to EC Directives
The W-series Servo Driver complies with EC Directives. To ensure that the machine or device
in which a Servo Driver and MC Unit are used complies with EC directives, the Servo System
must be installed as follows (refer to OMNUC W-series User’s manual (I531)):
1,2,3...
xvi
1. The Servo Driver must be mounted in a metal case (control box). (It is not necessary to
mount the Servomotor in a metal box.)
2. Noise filters and surge absorbers must be inserted in power supply lines.
3. Shielded cable must be used for I/O signal cables and encoder cables. (Use soft steel wire.)
4. Cables leading out from the control box must be enclosed within metal ducts or conduits
with blades.
5. Ferrite cores must be installed for cables with braided shields, and the shield must be directly grounded to a ground plate.
