Caution
Failure to follow instructions may result in injury or product damage.
01. Use the product within the rated specifications.
Failure to follow this instruction may result in fire or product damage.
02. Use a dry cloth to clean the unit, and do not use water or organic solvent.
Failure to follow this instruction may result in fire.
03. When connecting the power input and relay output, use AWG 18 (0.8mm
2
) cable
or over and tighten the terminal screw model with a tightening torque of 0.3 N m.
Use the copper-conductor wire with the temperature class 60℃.
Failure to follow this instruction may result in fire or malfunction due to contact failure.
04. Keep the product away from metal chip, dust, and wire residue which might flow
into the unit.
Failure to follow this instruction may result in fire, product damage or malfunction.
05. The durability of relay output depends on conditions of relay switching and load.
Be sure to test under actual operating conditions and use it within the appropriate
switching cycles without problem on product performance.
Failure to follow this instruction may result in fire or product damage.
06. Do not touch the relay output terminal immediately after the power source to the
load is disconnected.
Failure to follow this instruction may result in electric shock.
Cautions during Use
•
Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
•
The power input is insulated and limited voltage/current or use SELV, Class 2 power supply.
•
Connect a protective device (fuse etc.) to the safety output terminal for short-circuit,
overcurrent and ground fault protection.
Failure to follow this instruction may result in fire or malfunction.
•
Do not use AC and DC circuits together between safety output terminals.
-SFC-R212: between 13-14 terminal and 23-24 terminal
-SFC-R412, SFC-ER412: between 13-14 terminal and 23-24 terminal or between 33-34 terminal
and 43-44 terminal
-SFC-R212-R2□: between 13-14 terminal and 23-24 terminal or between 37-38 terminal and
47-48 terminal
•
Keep away from high voltage lines or power lines to prevent inductive noise. In case installing
power line and input signal line closely, use line filter or varistor at power line and shielded
wire at input signal line. Do not use the product near the equipment which generates strong
magnetic force or high frequency noise.
•
Do not drop the product or expose it to excessive vibration or shock. It may cause failure or
malfunction.
•
Be sure to turn off the power before connecting, inspecting and repairing the product. It may
cause malfunction or short circuit
•
When mounting the products close to each other, the rated current of the relay output is 3A.
Do not apply a current greater than 3A. If the current in the relay output flows 3A, or more,
make sure that the distance between the products should be 20mm or more.
•
Assessment of conformity to the required safety level is evaluated for the entire system.
Please consult with a certified certification body regarding the assessment procedure.
•
Be sure to set the off-delay time to maintain the safety function of the system. Set the setting
of off-delay switch on both the front and back sides to the same value. If you set it differently,
an error occurs.
•
For switches used for safety inputs, logic input and feedback start input, use a switch with
contacts capable of normally switching the micro loads (24 VDCᜡ, 5mA).
•
It should be done away regarded as an industrial waste. For more information, please refer to
laws, regulations and standards in the country or region.
•
This unit may be used in the following environments.
- Indoors (in the environment condition rated in ‘Specifications’)
- Altitude max. 2,000m
- Pollution degree 3
- Installation category Ⅲ
