• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in an unexpected opera-
tion.
• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.
• 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.
• After replacing Units, resume operation only after transferring to the new
CPU Unit and/or Special I/O Units the contents of the DM Area, HR Area,
and other data required for resuming operation. Not doing so may result in
an unexpected operation.
• When transporting or storing the product, cover the PCBs with electrically
conductive materials to prevent LSIs and ICs from being damaged by
static electricity, and also keep the product within the specified storage
temperature range.
• When transporting the Unit, use special packing boxes and protect it from
being exposed to excessive vibration or impacts during transportation.
• Do not attempt to disassemble, repair, or modify any Units.

EMC Directives
OMRON Units complying with EC Directives also conform to related EMC
standards making them easier to incorporate in other Units 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 sys-
tem used by the customer, however, must be checked by the customer.
EMC-related performance of OMRON Units complying with EC Directives will
vary depending on the configuration, wiring, and other conditions of the equip-
ment or control panel in which OMRON devices are installed. The customer
must, therefore, perform final checks to confirm that units and the overall sys-
tem conforms to EMC standards.
Note Applicable EMS (Electromagnetic Susceptibility) and EMI (Electromagnetic
Interference standards in the EMC (Electromagnetic Compatibility) standards
are as follows:
