6.2 Wiring method
1. Wiring method differs between the voltages, AC 100 / 110 V and 200 / 220 V. Bind the lead wires of the
coil according to the instruction on the label attached to the coil.
2. In order to prevent disconnection or insulation failure, avoid unnecessarily pulling the lead wires or
subjecting them to excessive load while wiring or use.
3. Use electric wires which have a core of 0.75 mm
4. Install a fuse (3A) to protect the electric circuit. In addition, if the product is used in a fuel supply system,
install a circuit protector of a rated capacity shown in the following.
• Rated voltage 100 / 110 V: 0.5 A circuit protector
• Rated voltage 200 / 220 V: 0.3 A circuit protector
5. When using a terminal box, do not rotate it to change its posture.
* Failure to follow this notice may cause disconnection or insulation failure.

6.3 Precaution for installation
Electric wiring work must be done by experienced professional.
1. If there is a risk of death, bodily injury or damage to property at the time of malfunction of the
product, be sure to install a suitable safety device that controls fluid flow interception/release or
sounds an alarm.
2. The product cannot be used as an emergency shutoff valve.
* The product is not designed as a safety valve such as an emergency shutoff valve. If the product
is applied to a system that needs safety measures, install other equipment besides the product to
ensure the safety.
3. The product is not explosion-proof. Do not use it in the area or ambience where explosive gases
accumulate.
* Using the product under the said conditions may cause fire.
4. Connect the cables only after confirming that no power is supplied.
* Failure to follow this notice may cause an electric shock.
5. Connect the cables according to the instructions after confirming the rated voltage.
* Erroneous cable connection may cause an electric shock or fire.
6. Do not supply electric power to the coil while it is detached from the valve.
* Failure to follow this notice may result in coil burnout or fire due to an overcurrent.
