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 stan-
dards 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 cus-
tomer 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): EN50081-2
(Radiated emission: 10-m regulations)
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).
6-3 Conformance to EC Directives
The CPM1A PCs (transistor output models) comply with EC Directives. Relay
output models do not conform to the EC Directives. To ensure that the machine
or device in which the CPM1A PC is used complies with EC directives, the PC
must be installed as follows:
1, 2, 3... 1. The CPM1A 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. CPM1A PCs complying with EC Directives also conform to the Common
Emission Standard (EN50081-2). 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 condi-
tions. You must therefore confirm that the overall machine or equipment
complies with EC Directives.
4. The CPM1A with relay output does not conform to the EC Directives. For
devices for use in the EC, use the CPM1, which meets the CE marking
requirements. Further information is available at any of the OMRON offices
or OMRON sales representatives listed on the inside back cover of this
manual.
6-4 CPM1A-MAD01 Conformance to EMC Directives
Immunity testing conditions when using the current I/O of the CPM1A-MAD01
are as follows.
• Total accuracy: +10%/-1%
• Insert the following core in each line as shown below.
