General Requirements for Using the FA-M3 Controller
Avoid installing the FA-M3 controller in the following locations:
- Where the instrument will be exposed to direct sunlight, or where the operating
temperature exceeds the range 0
°
C to 55
°
C.
- Where the relative humidity is outside the range 10 to 90%, or where sudden
temperature changes may occur and cause condensation.
- Where corrosive or flammable gases are present.
- Where the instrument will be exposed to direct mechanical vibration or shock.
- Where the instrument may be exposed to extreme levels of radioactivity.
Use the correct types of wire for external wiring:
- Use copper wire with temperature ratings greater than 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.
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 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).
Low impedance grounding:
- For safety reasons, connect the [FG] grounding terminal to a Japanese Industrial
Standards (JIS) Class D Ground
*1
(Japanese Industrial Standards (JIS) Class 3
Ground). For compliance to CE Marking, use braided or other wires that can ensure
low impedance even at high frequencies for grounding.
*1 Japanese Industrial Standard (JIS) Class D Ground means grounding resistance of 100 Ω max.
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” (IM34M6C11-
01E).
Keep spare parts on hand:
- Stock up on maintenance parts including spare modules, in advance.
