(10) Operating procedure
- Do not touch any parts on actuator circuit board or terminal block or connect or disconnect wires while
the actuator is energized. (Any such practice may result in an electric shock or equipment damage.)
- Keep hands and other extremities away from moving parts under all circumstances.
(Any such practice may get your hand, arm, or other part of your body caught.)
- Be sure to establish a ground. (A defective ground may result in an electrical shock, fire, or other incident.)
- At the time of adjustment or inspection, ensure that your hands are free of water and oil.
(Any such substance on your hands may result in an electric shock or equipment damage.)
- Before manual operation, ensure that the actuator is not activated by the motor.
- Do not connect two or more motor-driven valves in series. Also, install a switch (or a relay contact)
for each motor-driven valve.
- Do not use the product near a high-voltage wire, inverter or other equipment that produces electrical
noise or magnetism. (The presence of such nearby may cause malfunction or breakdown.)
- Check the integrity of wiring insulation before connecting to the actuator.
(Failure to observe this precaution may result in wire damage.)
- Ensure all covers are tightly fastened prior to operation.
(Insufficient fastening may allow rainwater, dust, or dirt to come in, resulting in breakdown.)
- When connecting wires, be sure to observe the connection diagram and make the connections correctly.
Moreover, after wiring, ensure that the connections are securely made before turning on the power.
(Failure to take this precaution may cause malfunction or breakdown.)
