• Changing the operating mode of the PC.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Resume operation only after transferring to the new CPU board the contents of
the DM and HR Areas required for resuming operation. Not doing so may result
in an unexpected operation.
• Do not pull on the cables or bend the cables beyond their natural limit. Doing
either of these may break the cables.
• Do not place objects on top of the cables. Doing so may break the cables.
• Under no circumstances should batteries be short-circuited between positive
(+) and negative (–) terminals, charged, disassembled, heated, or thrown into
fire.
• When replacing parts, be sure to confirm that the rating of a new part is correct.
Not doing so may result in malfunction or burning.
• When transporting or storing the CPM2B, cover the circuit boards in antistatic
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 malfunction or
damage.
• Do not touch the expansion I/O connecting cable while the power is being sup-
plied 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.

6-2 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 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).
