3. Do not connect, repair, or inspect the unit while connected to a power source.

Failure to follow this instruction may result in fire.

4. Check 'Connections' before wiring.

Failure to follow this instruction may result in fire.

5. Do not disassemble or modify the unit.

Failure to follow this instruction may result in fire.

6. Since Lithium battery is embedded in the product, do not disassemble or burn the unit.

Failure to follow this instruction may result in fire.

Caution

1. When connecting the power/sensor input and relay output, use AWG 20(0.50mm

tighten the terminal screw with a tightening torque of 0.74 to 0.90N . m.

Failure to follow this instruction may result in fire or malfunction due to contact failure.

2. Use the unit within the rated specifications.

Failure to follow this instruction may result in fire or product damage.

3. Use dry cloth to clean the unit, and do not use water or organic solvent.

Failure to follow this instruction may result in fire.

4. Do not use the unit in the place where flammable/explosive/corrosive gas, humidity,

direct sunlight, radiant heat, vibration, impact, or salinity may be present.

Failure to follow this instruction may result in fire or explosion.

5. Keep metal chip, dust, and wire residue from flowing into the unit.

Failure to follow this instruction may result in fire or product damage.
