Warning
1. Confirm the specifications.
If the voltage or temperature are outside the specification range, it may cause destruction,
malfunction,electric shock or fire.
2. Confirm the specifications of the connecting valve
Check that the electrical specification of the valve; rated voltage, leakage current, etc. conform
to the specifications of the controller.
If they are outside the specification range, it may cause destruction, malfunction, electric shock
or fire.
Caution
1.Avoid direct sunlight or ultraviolet ray.
It may break/ damage the resin parts.
2. Do not store in an atmosphere where the product may be exposed to water, solvents,
oils and chemicals.
This may cause rust and/or corrosion on the metal parts and deterioration of resin parts.
3. Do not use in environments where the product may be exposed to particles or dust.
This may cause burnout of electrical parts such as short circuits on the terminal block.
4. Do not store in a strong magnetic field atmosphere.
This may cause electrical components such as transistors to malfunction.
Warning
1. Install with the power turned off.
Touching the electrical connection of the valve controller (naked charging unit) may cause
electric shock. Be sure to turn off the power before working with this product.
2. Do not apply external force to the board or element.
Do not drop, hit or apply excessive shock to the product.
Even if the board body is not damaged, the element may be damaged and cause malfunction.
Caution
1. Allow for sufficient space for maintenance.
When installing the products, allow access for maintenance.
2. Tighten threads with the proper tightening torque.
If the screws are tightened in excessive of the specified torque range, it may damage the mounting
screws, mounting brackets, board, etc.
If the tightening torque is insufficient, the mounting screws and brackets may become loose.
