 General Requirements for Using the FA-M3 / e-RT3 Controller

Set the product in a location that fulfills the following requirements:
- INDOOR USE ONLY
- This product is an open equipment. The product must be installed in a metallic
panel enclosure with an impact rating IK08 or more.
- 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.
