Securely tighten screws: - Securely tighten module mounting screws and terminal screws to avoid problems such as faulty operation. - Tighten terminal block screws with the correct tightening torque as given in this manual. Refer to the hardware user's manual or the applicable user's manual for the appropriate tightening torque. z Securely lock connecting cables: - Securely lock the connectors of cables, and check them thoroughly before turning on the power. z Interlock with emergency-stop circuitry using external relays: - Equipment incorporating the FA-M3 controller must be furnished with emergencystop circuitry that uses external relays. This circuitry should be set up to interlock correctly with controller status (stop/run). z Ground for low impedance: - For safety reasons, connect the [FG] grounding terminal to a protective earth (Comply with the regulation of each country.). For compliance to CE Marking, use braided or other wires that can ensure low impedance even at high frequencies for grounding.
- 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). z 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. z 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.
- 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. z Avoid storing the FA-M3 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 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.
