EC Directives

• When transporting or storing the CPM2B, cover the circuit boards in anti-
static material to protect them from static electricity and maintain the
proper storage temperature.
• Before touching the Unit, be sure to first touch a grounded metallic object
in order to discharge any static build-up. Not doing so may result in mal-
function or damage.
• Do not touch the expansion I/O connecting cable while the power is being
supplied in order to prevent any malfunction due to static electricity.
• Do not touch CPM2B circuit boards or the components mounted to them
with your bare hands. There are sharp leads and other parts on the
boards that may cause injury if handled improperly.
• When disposing the product, observe local ordinances and regulations.

Concepts
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):
EN50081-2
(Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).

Conformance to EC Directives
The CPM2B PLCs comply with EC Directives. To ensure that the machine or
device in which the CPM2B PLC is used complies with EC directives, the PLC
must be installed as follows:
1,2,3...
1.
The CPM2B PLC 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.
CPM2B PLCs complying with EC Directives also conform to the Common
Emission Standard (EN50081-2). Radiated emission characteristics (10-m
