General Requirements for Using the FA-M3 / e-RT3 Controller

Set the product in a location that fulfills the following requirements:
- Where the product will not be exposed to direct sunlight, and where the operating
surrounding air temperature is from 0°C to 55°C (32°F to 131°F).
There are modules that must be used in an environment where the operating
surrounding air temperature is in a range smaller than 0°C to 55°C (32°F to 131°F).
Refer to “Hardware Manual” (IM 34M06C11-01E) or the applicable user's manual. In
case of attaching such a module, the entire system's operating surrounding air
temperature is limited to the module's individual operating surrounding air
temperature.
- Where the relative humidity is from 10 to 90%.
In places where there is a chance of condensation, use a space heater or the like to
constantly keep the product warm and prevent condensation.
- For use in Pollution Degree 2 Environment.
- Where there are no corrosive or flammable gases.
- Where the product will not be exposed to mechanical vibration or shock that exceed
specifications.
- Where there is no chance the product may be exposed to radioactivity.

Use the correct types of wire for external wiring:
- USE COPPER CONDUCTORS ONLY.
- Use conductors with temperature rating above 75°C.

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 Manual” (IM 34M06C11-01E) or the applicable
user's manual for the appropriate tightening torque.

Securely lock connecting cables:
- Securely lock the connectors of cables, and check them thoroughly before turning
on the power.

Interlock with emergency-stop circuitry using external relays:
- Equipment incorporating the FA-M3 / e-RT3 controller must be furnished with
emergency-stop circuitry that uses external relays. This circuitry should be set up to
interlock correctly with controller status (stop/run).

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.

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.
