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 EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN61131-2
EMI (Electromagnetic Interference):
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75
to 1,500 VDC meet the required safety standards for the PC (EN61131-2).
The CPM2C PCs comply with EC Directives. To ensure that the machine or
device in which the CPM2C PC is used complies with EC Directives, the PC
must be installed as follows:
1. The CPM2C PC 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. Basic insulation is provided between the commons of different polarities of
the output relay for the CPM2C-20@@R (model with 20 relay output
points).
When connecting devices that operate at voltages higher than 50 VAC and
those that operate on DC power supplies to adjoining relay output termi-
nals, use different DC power supplies for output devices from those for in-
put devices and the CPM2C power supply.
4. CPM2C PCs complying with EC Directives also conform to the Common
Emission Standard (EN61000-6-4). Radiated emission characteristics
(10-m regulations) may vary depending on the configuration of the control
panel used, other devices connected to the control panel, wiring, and other
conditions. You must therefore confirm that the overall machine or equip-
ment complies with EC Directives.
