 Configure and route cables with noise control considerations:
- Perform installation and wiring that segregates system parts that may likely become
noise sources and system parts that are susceptible to noise. Segregation can be
achieved by measures such as segregating by distance, installing a filter or
segregating the grounding system.
 Configure for CE Marking Conformance:
- For compliance to CE Marking, perform installation and cable routing according to
the description on compliance to CE Marking in the “Hardware Manual” (IM
34M06C11-01E).
- The list of CE conforming models is available in Appendix A2. of “Hardware
Manual”.
 Keep spare parts on hand:
- We recommend that you stock up on maintenance parts, including spare modules,
in advance.
- Preventive maintenance (replacement of the module) is required for using the
module beyond 10 years.
 Discharge static electricity before touching the system:
- Because static charge can accumulate in dry conditions, first touch grounded metal
to discharge any static electricity before touching the system.
 Wipe off dirt with a soft cloth:
- Gently wipe off dirt on the product's surfaces with a soft cloth.
- If you soak the cloth in water or a neutral detergent, tightly wring it out before wiping
the product. Letting water enter the module interior can cause malfunctions.
- Do not use volatile solvents such as benzine or paint thinner or chemicals for
cleaning, as they may cause deformity, discoloration, or malfunctioning.
 Avoid storing the FA-M3 /e-RT3 controller in places with high
temperature or humidity:
- Since the CPU module has a built-in battery, avoid storage in places with high
temperature or humidity.
- Since the service life of the battery is drastically reduced by exposure to high
temperatures, take special care (storage surrounding air temperature should be
from -20°C to 75°C).
- There is a built-in lithium battery in a
Sequence CPU
module which serves as backup
power supply for programs, device information and configuration information.
The service life of this battery is more than 10 years in standby mode at room
temperature. Take note that the service life of the battery may be shortened when
installed or stored at locations of extreme low or high temperatures. Therefore, we
recommend that modules with built-in batteries be stored at room temperature.
 Always turn off the power before installing or removing modules:
- Failing to turn off the power supply when installing or removing modules, may result
in damage.

Do not touch components in the module:
- In some modules you can remove the right-side cover and install ROM packs or
change switch settings. While doing this, do not touch any components on the
printed-circuit board, otherwise components may be damaged and modules may fail
to work.
