WARNING
1) Turn OFF the Power Supply to do the electrical connection.
Never try to work on it on keeping the electricity turned ON.
2) Make sure to have the steady grounding. You have a risk of getting
electrical shock when the machine caused a failure or electrical
leakage.
The screw of the earth terminal at the motor side is provided with
an “earth mark” in the terminal box.
Use power cords of the same diameter for the motor and earth.
3) Use the pump only at the rated voltage. Use at other than the rated
voltage will interfere with correct operation of the overload
protector, and result in the motor burning out, or fire.
4) The connector in the terminal box, with 380V-460V and 200V-240V
power supply voltage, please change the wiring.
WARNING
1) Be sure to put an overload protective device conforming to the
motor capacity.
You have a risk that the Motor burns out or causes a fire if you have
not put such an overload protective device or put a device not
conforming to the motor capacity.
You are also recommended to put a dedicated ground-fault
interrupter.
2) Do the correct wiring work conforming to the Electrical Installation
Technical Standard and Internal line cord. Wrong wiring work might
cause a fire.
3) The larger cable gland is for wires having a diameter of φ8 to φ13,
and the smaller one is for wires having a diameter of φ5 to φ8. Use a
cable gland that is suitable for the size of the power cord to be used.
(Refer to fig.2 and fig. 3)
4) Never fail to close the Terminal box cover to operate the Pump.
