WARNING
Turn OFF the Power Supply to do the electrical connection.
Never try to work on it on keeping the electricity turned ON.
A correct wiring work must observe the law and the rule that relates safely.
A wrong wiring work might start a fire.
The measures such as lockout/tag out should be executed not so as to
turn the power switch by mistakes during working.
You have a risk of getting electrical shock when the machine caused a
failure or electrical leakage.
Make sure to have the steady grounding.
You are also recommended to install a dedicated earth leakage breaker.
The screw of the earth terminal at the motor side is provided with an “earth
mark
” in the terminal box.
The diameter of the cable to connect to a ground is the same as a cable
supplying a power supply in a motor at least.
Be sure to ground the motor ground terminal
200V - 240V: Ground to 100ohm or less
380V - 460V: Ground to 10 ohm or less
Use a safety circuit which keeps the motor from starting a fire which is
caused by over current.
Install a safety circuit suitable for the capacity of the motor. If a safety
circuit is not installed, or if a safety circuit that is unsuitable for the motor
capacity is installed, the motor will be damaged leading to fire.
The safety circuit must use the one that operates by the ratings current
value of the motor that uses it.
Do the setting of the safety circuit in a rating current value of the motor in
line with the voltage and the frequency of the power supply.
When a motor is different from the standard, please do the setting of the
safety circuit in a rating current value of the motor you use.
Never fail to close the Terminal box cover to operate the Pump.
Do not use it excluding the voltage rating of the motor. It causes damaging
by a fire and a fire of the motor.
CAUTION
Do the Direct-in start connection.
