6-3 Conformance to EC Directives
Perform wiring according to specified procedures.
Before touching a Unit, be sure to first touch a grounded metallic object in order to
discharge any static build-up. Not doing so may result in malfunction or damage.
Do not drop the Unit or subject it to abnormal shock or vibration.
Confirm the safety of the destination node before transferring a program to the node or
changing the contents of I/O memory. Doing either of these without confirming safety
may result in injury.
• 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 (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 overall machine conform to EMC standards.
Applicable EMC (Electromagnetic Compatibility) standards are as follows:
• EMS (Electromagnetic Susceptibility): EN61000-6-2
• EMI (Electromagnetic Interference): EN61000-6-4
(Radiated emission: 10-m regulations)
The CJ1W-MCH72 complies with EC Directives. To ensure that the machine
or device in which a CJ1W-MCH72 is used complies with EC Directives, the
CJ1W-MCH72 must be installed as follows:
1 The CJ1W-MCH72 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.
3 Units complying with EC Directives also conform to the Common Emission
Standard (EN61000-6-4). With regard to the radiated emission (10-m
regulations), countermeasures will vary depending on the devices
connected to the control panel, wiring, the configuration of the system, and
other conditions. The customer must, therefore, perform final checks to
confirm that devices and the overall machine conform to EC Directives.
